Junkbuster
Junkbuster is a simple
non-caching web proxy designed to remove banner ads and cookies. It
was the main model for WWWOFFLE's (and therefore Polipo's) header and
ad-removing features.
Junkbuster's HTTP support is very simple (some would say broken): it
doesn't do persistent connections, and it breaks horribly if the
client tries pipelining. Junkbuster is no longer being maintained,
and has evolved into Privoxy.
