Local web cache for restricted users question
I am in charge of a project to teach 20 or so inmates basic computer skills. These people cannot have outside access to the web, but I need to show them how to do a basic Google search and search for articles on Wikipedia. (also needs to be Arabic and English)

I was thinking of using a squid proxy to cache all the sites on the server and then let them go to the predesignated sites and perform the predesignated searches. This method would probably be fine for me but the people teaching the class would have issues updating the cache with new content. (also I can't get squid to retain it's cache for over 1yr)

My question is, is there an easier method of doing this preferably with a web GUI to update the cache. Is their some easier method I could be using?

polipo

POLIPO(1)						      General Commands Manual							 POLIPO(1)

NAME

       polipo - a caching web proxy

SYNOPSIS

       polipo [ -h | -v | -x ] [ -c config ] [ var=val ]...

DESCRIPTION

       Polipo  is a caching HTTP proxy.  It listens to requests for web pages from your browser and forwards them to web servers, and forwards the
       servers' replies to your browser.  In the process, it optimises and cleans up the network traffic.

       By default, Polipo listens on TCP port 8123.  Please configure your web browser to use the proxy on localhost port 8123.

OPTIONS

       -h     Display help and exit.

       -v     Display the list of configuration variables and exit.

       -x     Purge the on-disk cache and exit.

       -c     Select an alternate configuration file.

       var=val
	      Change the value of a configuration variable.

FILES

       /etc/polipo/config
	      The default location of Polipo's configuration file.

       /etc/polipo/forbidden
	      The default location of the list of forbidden URLs.

       /var/cache/polipo/
	      The default location of the on-disk cache.

       /usr/share/polipo/www/
	      The default root of the local web space.

SIGNALS

       SIGUSR1
	      write out all in-memory objects to disk and reload the forbidden URLs file.

       SIGUSR2
	      write out all in-memory objects to disk, discard all in-memory objects, and reload the forbidden URLs file.

       SIGTERM, SIGINT, SIGHUP
	      write out all in-memory objects to disk and quit.

SECURITY

       The internal web server will follow symbolic links that point outside the local document tree.  You should run Polipo in a chroot  jail	if
       that is a problem.

       There is no reason to run Polipo as root.

FULL DOCUMENTATION

       The full manual for Polipo is maintained in a texinfo file, and is normally available through a web server internal to Polipo.  Please make
       sure that Polipo is running, and point your favourite web browser at

	      http://localhost:8123/

       Alternatively, you may type

	      $ info polipo

       at a shell prompt, or

	      C-h i m polipo RET

       in Emacs.
