[c-nsp] OT: Proxy server that can insert content

[Matt Stockdale]

  Sounds like something you could do with squid, and using an external
redirector program. I use a setup like this to run an ad-filtering proxy
(Squid + addzapper.sourceforge.net/wrapzap, zapchain, squirm), so I
imagine it wouldn't be difficult to write one in $scripting_language to
output a page every x connections per originating IP.

Since it's going to see the URL (and should know about referrer, etc),
you could conceivably also generate your announcements with a link to
wherever the user had been headed before you hijacked them.

Besides, you want to use squid anyway, so once you have that going you
are halfway there.

Good luck.

Matt
