Transparent Proxy with URL Rewriting
All traffic on the LAN is routed through a single machine and filtered using iptables. I'd like to redirect this traffic to a transparent proxy running on the same machine that will rewrite the URL if it matches a specified regex, in which case the user will be redirected to a local server. In other words, all HTTP requests should flow through as usual unless the user attempts to navigate to, say, "xyz.com," in which case the proxy will send the user to Apache running locally with a page displaying something like "Sorry, you can't go here." I have already investigated Squid and its URL rewriting component, but it seems terribly complicated to configure and a bit overkill since I won't be using 98% of its other features. Is there a free program other than Squid I could use, or perhaps someone could provide me with some resources for writing a program myself if it isn't too complicated?

squid_radius_auth

squid_radius_auth(8)                                          System Manager's Manual                                         squid_radius_auth(8)

NAME

       squid_radius_auth - Squid RADIUS authentication helper

SYNOPSIS

       squid_radius_auth -f configfile
       squid_radius_auth -h "server" [-p port] [-i identifier] -w secret

DESCRIPTION

       This helper allows Squid to connect to a RADIUS server to validate the user name and password of Basic HTTP authentication.

       -f configfile
              Specifies the path to a configuration file. See the CONFIGURATION section for details.

       -h server
              Alternative method of specifying the server to connect to

       -p port
              Specify  another  server  port where the RADIUS server listens for requests if different from the default RADIUS port.  Normally not
              specified.

       -i identifier
              Unique identifier identifying this Squid proxy to the RADIUS server.  If not specified the IP address is used  as  to  identify  the
              proxy.

       -w secret
              Alternative method of specifying the shared secret. Using the configuration file is generally more secure and recommended.

       -t timeout
              RADIUS request timeout. Default 10 seconds.

CONFIGURATION

       The configuration specifies how the helper connects to RADIUS.  The file contains a list of directives (one per line). Lines beginning with
       a # is ignored.

       server radiusserver
              specifies the name or address of the RADIUS server to connect to.

       secret somesecretstring
              specifies the shared RADIUS secret.

       identifier nameofserver
              specifies what the proxy should identify itsels as to the RADIUS server.  This directive is optional.

       port portnumber
              Specifies the port number or service name where the helper should connect.
