I have this cgi file running on CentOS 5 with Apache 2.2.3 and although it executes most fields are empty, a typical block by squidGuard yields this: Supplementary info : Client address = 192.168.0.5+clientname Client name = User ident = Client group = URL = Target class = The redirect lines is: http://localhost/cgi-bin/squidGuard-simple.cgi?clientaddr=%a+clientname=%n+clientuser=%i+clientgroup=%s+targetgroup=%t+url=%u3 I assume the "+" throws this off somehow, something to do with cgi and apache? Any ideas? Thanks! jlc
