Re: [Devil-Linux-discuss] Reverse Proxying with Devil Linux

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello,

I got squid working now, with a slightly modified script.

It was missing a group and others' execute bit in rewrite proc,
stupid error sorry.

So I stick with squid now.
The rewrite script is now like this:

#!/usr/bin/perl -p
BEGIN { $|=1; }
s%^http://www.company.com%http://www.company.vpn% && next;

One line can be added per backend

Brgs, Pekka
