Finding information on the Web


Viewing a page

When you first start Netscape Communicator, you normally see Navigator, which is your browser. The first page you see is your Home page--the page that appears automatically each time you start Navigator.

By the way: Some pages are divided into rectangular areas called frames. Each frame on a page can display other pages, like the picture-in-picture feature of television sets. Sometimes clicking inside one frame affects activity inside another frame.

To refresh the current page, reflecting any changes made while it has been on your screen, click Reload.

To view more than one page at a time:

The new window displays another copy of your home page on the screen in a second Navigator window. The new window is independent of the other Navigator window--you can view two different pages in the two windows.


Moving to another page

There are two ways to move to another page: you can type a URL, or click a link.

A URL is a page's location (address) on the Web. If you know a page's URL, you can type it in:

  1. Type the URL into the "Location:" field. (Sometimes you'll see "Netsite:" instead of "Location:", if the current page is from Netscape.) You can type all or part of the URL; for instance, you can leave off the prefix "http" and the suffix "index.html". On Windows, if you type part of a URL you've previously visited Navigator tries to fill in the rest of the letters.

  2. Press Enter (Return on the Mac OS).

    Links are places on a page that point to other pages. Links are usually highlighted or underlined; they can be text or pictures. To move by clicking a link:

    1. Move the mouse so the cursor moves around on your screen. You'll see the cursor change to the pointing finger in some places: these are links.
    2. Click the link. While the network locates the page the link points to, you can check the status messages at the bottom of the window.

    If you change your mind and don't want to view a page, click Stop.

    By the way: You can learn information about links by looking at them and at their URLs. (When you point to a link, its URL is displayed in the status field at the bottom of the window.)

    The Open Page dialog

    If you know the URL of a page you want to visit, you can use the Open Page dialog (Open Location in Navigator on the Mac OS).

    On Windows and Unix:

    1. Open the File menu and choose Open Page.

    2. Click the Navigator button.

    3. Type the URL of the page you want to visit. (You can also open local files on your computer's hard disk by clicking Choose File.)

    4. Click Open.

    On the Mac OS:

    1. Open the File menu, drag to the Open option, and choose Location in Navigator.

    2. Type the URL of the page you want to visit. (You can also open local files on your computer's hard disk by clicking Choose File.)

    3. Click Open.

    Retracing your steps

    The simplest way to retrace your steps is using the Back and Forward buttons.

    If repeatedly clicking the Back button is tedious, do this:

    On Windows only, another simple method is to use the Location field's popup menu.

    Retracing your steps in detail: the History list

    Navigator maintains a history list of pages you have recently viewed in the past several days. (The exact number of days tracked depends on how your Navigator preferences are set up.) Navigator uses the history list for the Back and Forward buttons and the Go menu.

    The History list contains the most comprehensive history information. To view the entire list:

    To view a page, double-click its line in the list.

    To sort the pages in the history list (Windows and Unix only)

    1. From the Communicator menu, choose History to open the History window.

    2. From the History window's View menu, choose whether you wish to sort by title, location, dates, or number of visits.

    3. From the History window's View menu, choose whether you wish to sort in ascending (A to Z, new to old, 1 to 9) or descending (Z to A, old to new, 9 to 1) order.

    To search for pages in the history list (Windows only)

    1. From the Communicator menu, choose History.

    2. From the History window's Edit menu, choose Search History List.

    3. From the Search History List dialog, click the first pop-up menu and choose a search by page title, location, or various date information.

    4. Click the second pop-up menu and choose an option. Choose "is" if you know exactly what you're searching for; choose "contains" if you know only part of what you're searching for. Choose "isn't" or "doesn't contain" to exclude pages from your search.

    5. Click the third field and type all or part of the title, location, or other information you want to search for (or exclude).

    6. (Optional) To further constrain the search, click More one or more times. This lets you enter additional search criteria. To reverse this action, click Fewer.

    7. Click Search. Pages matching your search criteria are listed.

    When you're done searching, you can:


    Checking a page's security

    You can view information that helps you establish a page's authenticity and other security characteristics:

    In the upper portion of the Info window, you can see a list of the component URLs that make up the page: for example, the URLs of any image files contained in the page.

    The lower portion of the window lists information about the page's location, type, source, cache, length, modification date, and character-set encoding, as well as details about the page's security status. You can find out if the page is encrypted or not encrypted, and the encryption type for transmission and server certification.

    If a page is encrypted, the security information tells you the encryption grade, export control, key size, and algorithm type. In addition, the server certificate identifies:

    Who the certificate belongs to (the organization)
    Who the certificate was issued by
    Serial number
    Valid certificate dates
    Certificate fingerprint (composed of hexadecimal digits)

    Like pages, certificate information is protected by encryption to ensure authenticity and integrity. The information can include the following:

    The server's fully qualified common or host name (such as hostname.netscape.com)
    Department name (optional)
    Legal, registered organization name
    Locality or city the organization resides in or is registered in
    State or province name
    Country name

    To view general security information and work with Communicator's encryption and certificate features:

    In the Security Info window, click Help for more instructions.


    Checking a page's technical details

    You can view the source code (HTML and other code) that generates a web page:


    Searching within a page

    To find text within the page you are currently viewing:

    1. From the Edit menu, choose Find in Page. If the page you are viewing contains frames, you may need to click within a frame first.

    2. In the Find dialog box, type the text you want to find.

    3. Select the Match case checkbox (Case Sensitive on the Mac OS and Unix) if capital letters should be matched.

    4. On Windows, select Up or Down to direct the search toward the beginning or end of the page. If there is a current selection, the search begins at the selection and does not wrap around to the beginning of the page. On the Mac OS and Unix, select the Find Backwards checkbox to start the search from the beginning or end of the page.

    5. Click Find Next (Find on the Mac OS) to begin the search.

    To find the same word or phrase again:


    Bookmarking your favorite Web sites


    Creating a bookmark

    To bookmark a Web page:

    To revisited a bookmarked Web page:

    1. Click Bookmarks in the Location toolbar. On the Mac OS, open the Bookmarks menu--identified by a green bookmark icon to the right of the Go menu.

    2. Click the name of a bookmarked page.

    You can create bookmarks from any HTML file containing links. The links are placed in a folder in the bookmark list. To import HTML files (or hotlists) as bookmarks:

    1. If you are importing a hot list, first convert it to HTML. Several downloadable utilities perform this conversion. You can also use another browser's mail command to transmit a hotlist in HTML format.

    2. Open the Bookmarks menu and choose Edit Bookmarks. On the Mac OS, open the Communicator menu and choose Bookmarks.

    3. In the Bookmarks window, open the File menu and choose Import.

    4. In the Import Bookmarks File dialog, select the file you want to import.

    5. Click Open.

    Creating an Internet shortcut

    An Internet shortcut lets you jump to a Web page from your desktop or from folders on your computer. There are three ways to create Internet shortcuts.

    To create a shortcut from a link:

    To create a shortcut using the bookmark icon:

    Can't find the bookmark icon? On color screens, the bookmark icon is green. It's small, and located in the Location toolbar near the word "Location:" (sometimes replaced by the word "Netsite:").

    What is MIME? MIME is Multipurpose Internet Mail Extensions, a standard that permits non-text files (such as images) to be attached to email messages and sent over the Internet. For instance, a TIFF image file's MIME type is "image/tiff." If you don't know the MIME type for a particular kind of file, you can leave the field blank.

    When a Web page contains information that requires a helper application, it is often in a file that must be downloaded. This simply means that the file must be copied onto your hard disk before you can view it using the helper application.

    To edit a file type and specify how to handle downloaded files:

    1. From the Edit menu, choose Preferences.

    2. Click the Navigator category; then click Applications.

    3. Select one file type from the list and click Edit.

    4. Edit the fields as desired.

    5. Select an action in the "Handled By" area of the panel. You can designate:

      • Navigator (Communicator on the Mac OS). This opens a downloaded file in the Navigator window if the file's format is supported.

      • Save to Disk. This saves a file downloaded on your hard disk.

      • Application. This opens the downloaded file in an application. To select the application, click Browse (Choose on the Mac OS).

    6. Check "Ask me before opening downloaded files of this type" if you want a dialog box notification before downloading files that are handled by applications other than Navigator.

    7. Click OK.

    To remove an existing application and associated file type:

    1. From the Edit menu, choose Preferences.

    2. Click the Navigator category; then click Applications.

    3. Select one file type from the list and click Remove (Delete on the Mac OS and Unix).

    4. Click OK.

    (Mac OS and Unix only) Communicator temporarily stores downloaded files on your disk. You can select a new default folder if, for example, your disk is short on space and you want to store temporary files elsewhere. To specify a folder:

    1. From the Edit menu, choose Preferences.

    2. Click the Navigator category; then click Applications.

    3. Click Choose.

    4. A dialog opens listing the folders, files, and applications on your computer. Find the folder you want and double-click to select it.

    5. Click OK to close the Preferences window.

    Improving speed, efficiency and security


    Speeding things up

    There are two types of settings that affect speed: the automatic loading settings, and the cache settings. (You can also speed things up by limiting downloads of long email messages. See Saving disk space).

    Automatic loading

    When you bring a Web page to your screen, Communicator automatically loads (starts up) several features that help interpret Web pages. These features can make Web pages more lively, but they take time to load. If you like, you can turn off automatic loading.

    1. From the Edit menu, choose Preferences.

    2. Click the Advanced category.

    3. To turn automatic loading on or off, click to the checkbox next to one or more of the following:

      • Automatically load images. If selected, images in a Web page are displayed when you view the page. If unselected, images are replaced by small icons, and you click the Images button in the toolbar to view the images.

      • Enable Java. If selected, allows Java applets (small programs that add functionality to pages) to run automatically.

      • Enable JavaScript. If selected, allows JavaScript (commands that add functionality to pages) to run automatically.

      • Enable style sheets. If selected, pages formatted by style sheets are displayed as the author intended. If unselected, author's formats aren't included.

      • Enable Autoinstall. If selected, allows Communicator software to be automatically updated over your office or organization's network. (In some organizations, this is pre-determined by a system administrator.)

      • Send email address as anonymous FTP password. If selected, your email address is transmitted automatically when you log on to a public FTP (file transfer protocol) site. FTP sites are used for transferring files.

    4. Click OK.

    Cache settings

    The cache is a part of your computer's hard disk and memory where copies of frequently-accessed Web pages can be stored. Then the computer already has the page and doesn't have to retrieve it from the network each time you want to view it.

    To set the size of or clear the memory cache (Windows and Unix only):

    1. From the Edit menu, choose Preferences.

    2. Click the Advanced category; then click Cache.

    3. Enter a number in the Memory Cache field to specify the size of the memory cache. The default is 1024K on Windows, 3000K on Unix.

    4. Click OK to close the Preferences window.

    To set the size of the memory cache (Mac OS):

    1. Quit Communicator. You may want to print these instructions first.

    2. Click the Communicator icon to select it (but don't start Communicator).

    3. Open the File menu and choose Get Info.

    4. In the fields next to Minimum Size and Preferred Size, specify the size of the memory cache.

    To set the size of the disk cache:

    1. From the Edit menu, choose Preferences.

    2. Click the Advanced category; then click Cache.

    3. Enter a number in the Disk Cache field to specify the size of the disk cache. The default is 7680K (5000K on Unix).

    4. (Optional) To specify where the disk cache should be stored, click Choose Folder. A dialog opens listing the items on your computer. Find the folder you want and double-click to select it.

    5. Click OK to close the Preferences window.

    By the way: When you exit from Communicator, cache maintenance is done. If you find that exiting takes longer than you wish, try reducing the size of the disk cache.

    You can specify how often Navigator checks the network for page revisions, to make sure you see an updated page from a network server rather than a potentially "stale" page stored in the cache.

    1. From the Edit menu, choose Preferences.

    2. Click the Advanced category; then click Cache.

    3. Select Once Per Session, Every Time, or Never. "Every Time" assures that the page you see is always the latest, at the cost of slower performance. "Never" is fastest, but the page you see might be stale.

    4. Click OK to close the Preferences window.

    To refresh a page at any time, click Reload. The computer checks the network to make sure you have the latest version of the page. To retrieve a fresh copy of a page regardless of what's in the cache, hold down the Shift key (Option key on the Mac OS) and click Reload

    If you find that pages that should be in the cache are taking longer to appear than they should, make sure the preference is not set to Every Time, because the verification requires a network connection that takes time.


    Improving security

    There are many things you can do to improve the security of your connection to the Web. Two things--controlling cookies and setting proxy values--are discussed in this section. For more security information, see [CROSS REFERENCE TO GO HERE].

    Cookies

    A "cookie" is a small amount of information that a Web site copies to your hard disk. A cookie can help a Web site identify you the next time you visit. For instance, if you shop for books online, the bookstore's Web site might store information about your favorite subjects in your cookie, and later use that information to recommend particular books.

    You can control your computer's behavior with respect to cookies:

    1. From the Edit menu, choose Preferences.

    2. Click the Advanced category.

    3. Select one of the following:

      • Accept all cookies

      • Accept only cookies that get sent back to the originating server (disables transmission of cookies to servers other than the server that originated the page)

      • Disable cookies

    4. Click "Warn me before accepting a cookie" to be notified when Communicator accepts a cookie.

    Important: Unless you're worried about the security of some of the Web sites you visit, you should choose to accept all cookies for a better Web experience.

    Setting proxy values

    Many organizations that have their own networks block access from the Internet to their networks. This prevents outside parties from gaining access to sensitive information. The protection is called a firewall.

    If your organization has a firewall, Communicator may need to go through a proxy before connecting you to the Internet. You can set Communicator to work with the proxy.

    Before you start:

    To set Communicator to work with the proxy:

    1. From the Edit menu, choose Preferences.

    2. Click the Advanced category and choose Proxies.

    3. Select one of the following:

      • "Direct Connection to the Internet" if you don't have to go through a proxy.

      • "Automatic proxy configuration" if you have a proxy configuration file. Type the file's URL in the field and click Reload.

      • "Manual proxy configuration" if you don't have a proxy configuration file. Click View (Configure on the Mac OS); type your settings and any exceptions in the Manual Proxy Configuration dialog (see Details). Then click OK.

    4. Click OK to close Preferences.

    Details about manual proxy configurations:

    Your computer may connect to several different servers (computers that handle networking matters). Each server handles a specific type of network service, such as communicating with HTTP sites or dealing with security. For each server, your manual configuration must specify which server runs the proxy software.

    Under "Address of proxy server to use," type the name or numberic IP address of the proxy server for each type of server (HTTP, Security, FTP, Socks, Gopher, and WAIS). Often a single proxy server handles the three major types of server: HTTP, FTP, and Gopher. Under "Port" type each proxy server's port number.

    Under Exceptions type the names of any domains that you can connect to directly, bypassing the proxy. For instance, if you type "adomain, bdomain, netscape.com" in this field, then the proxy will be bypassed each time you view a Web page or use another service from one of those domains. (Domain names are the part of a URL that contains the name of an organization, business, school, and so forth--such as netscape.com or www.washington.org. If you use local hostnames without the domain name, list them the same way. Multiple hostnames are separated by commas, and the wildcard character [*] cannot be used.)


    Saving disk space

    Downloading email can consume disk space. You can limit the disk space taken up by email:

    1. From the Edit menu, choose Preferences.

    2. Click the Navigator category; then click Disk Space.

    3. To limit the size of messages you download, click "Do not download any message larger than".

    4. Type the maximum size of messages that can be downloaded.

    5. To keep message folders compact, click "Automatically compact folders when it will save over".

    6. Type a size; when it is possibly to save disk space equal to the number you type, message folders will be automatically compacted.

    7. Click OK to close Preferences.

    To specify how long discussion messages are kept available:

    1. From the Edit menu, choose Preferences.

    2. Click the Navigator category; then click Disk Space.

    3. Click one of three buttons under "When it's time to clean up messages" to specify when newsgroup messages should be deleted.

    4. Unless you chose "Keep all messages," type the number of days to keep messages or the number of newest messages to keep.

    5. To delete read messages immediately, click "Keep only unread messages."

    6. (Windows only) To save disk space by retaining only message subject lines, click More Options, click "Remove message bodies only older than," and type the number of days to keep message bodies.

    You can also save disk space by setting a smaller disk cache. See Cache settings.


    Working Offline


    Offline preferences (not available on Unix)

    If you're using a modem connection, you might want to work offline, and go online only when you need to connect to the network. This can reduce online time and costs.

    1. From the Edit menu, choose Preferences.

    2. Click the Offline category.

    3. Select one of the following:

      • Online Work Mode to begin a network connection each time you start Communicator. If you use a network that connects you to the Internet continuously, this mode is optimal.

      • Offline Work Mode to not start a network connection each time you start Communicator.

      • Ask Me if you want to be asked, when starting Communicator, if a network connection should be made.

    If you choose Online Work Mode or Offline Work Mode, then you can choose to begin or end a network connection by opening the File menu and choosing Go Offline/Go Online. You can also choose to download mail or selected discussion groups, and send messages in your Outbox just before disconnecting or just after connecting to the network. If you choose Ask Me, these choices will be presented automatically when you start Communicator.


    Download preferences (not available on Unix)

    You can download messages--that is, read them offline without maintaining a network connection.

    1. From the Edit menu, choose Preferences.

    2. Click the Offline category; then click Download.

    3. Select one of the following:

      • Download Only Unread Messages to see only those messages you haven't yet read.

      • Download By Date to download messages according to their age. Use the radio buttons and pop-up menu to specify a time period.

    4. To specify which messages to download, click the Select Messages button (Download Items pop-up menu on the Mac OS) and click to highlight the mail folders or discussion groups you want.

    5. Click OK, then click OK again to close Preferences.
