A long time ago I decided to mess around with the redirect_program feature of squid. If you’re not familar with squid I suggest looking up the wiki on it http://en.wikipedia.org/wiki/Squid_(software).

What exactly does redirect_program do? No one knows for sure, some say that it is the very reason the internet works, while others speculate that the previous statement is nothing but rubish. The world may never know, however just because we don’t know what it does doesn’t mean we can’t use it!

Ok but seriously what does the redirect_program tag actually allow us to do. This tag is used to specify the location of the executable for the URL redirector. So you can basicaly create a program that can rewrite the requested URLs that are passing though squid. So one could play around with the data that is passing though squid pretty much on the fly. What is great about it, is that it’s very easy to program for and has many real world uses.

None of which we will talk about here.
