Squirm is a URL redirector for squid.
It provides a fast means for squid to modify URLs according to a set
rule that the administrator applies.
It is useful for things like
a) redirecting requests for common files to internal cached copies
b) restricting access to URLS and redirecting them to some other
place (a warning message for instance)
c) (and this is what I mostly use it for) redirecting things like
banners and ads to some other place.
