Proxies (Best?)

I hope this is the right place to post this. If not, would an administrator please move it? Thanks.

I've got a situation where we are using iPlanet proxy server to allow some of our web browsers to ONLY go to certain sites on an "approved" list. If they try to go to sites that aren't on the list, they get a message stating that they are at a limited workstation. This would be great overall if the iPlanet proxy (running on Win2K) wasn't so flakey. The performance seems poor because our clients complain about pages not loading completely or at all at times. I've been looking at Freshmeat.net for a decent open source/free software replacement. But there are quite a few proxies and they all seem to have different focuses.

What I need is just an HTTP proxy that will allow me to maintain a list of approved sites. Ideally, it should have a web interface for managing the approved sites since I'm not really the maintainer, a non-technical person is. And finally, the list should work with regular expressions so that wildcards can be used to allow people access to subparts of the approved sites. If possible, we really DON'T want stuff caching on disk because we can't afford to be legally viewed as a "content provider". Since the definition of that is pretty nebulous it makes the non-caching feature pretty important. Anyone know of anything like that?

Apache2 reverse proxies implementation

Hi all, I hope someone here could shine a light on an issue that I am having with apache2. I have 2 servers with apache2 on each, which are on the same network with one router. I have implemented what I have seen on guides on the net on the landing server such as 'Apache2 reverse proxies'...

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

NAME

       micro_proxy - really small HTTP/HTTPS proxy

SYNOPSIS

       micro_proxy

DESCRIPTION

       micro_proxy  is	a  very small HTTP/HTTPS proxy.  It runs from inetd, which means its performance is poor.  But for low-traffic sites, it's
       quite adequate.	It implements all the basic features of an HTTP/HTTPS proxy, in only 260 lines of code.

       To install it, add a line like this to /etc/inetd.conf:
	   webproxy  stream tcp nowait nobody  /usr/sbin/micro_proxy micro_proxy
       Make sure the path to the executable is correct.  Then add a line like this to /etc/services:
	   webproxy   port/tcp
       Change "port" to the port number you want to use - 3128, or whatever.  Then restart inetd by sending it a "HUP" signal, or rebooting.

       On some systems, inetd has a maximum spawn rate - if you try to run inetd services faster than a certain number of  times  per  minute,	it
       assumed	there's  either  a  bug of an attack going on and it shuts down for a few minutes.  If you run into this problem - look for syslog
       messages about too-rapid looping - you'll need to find out how to increase the limit.  Unfortunately this varies from OS to OS.	 On  Free-
       BSD,  you  add  a  "-R 10000" flag to inetd's initial command line.  On some Linux systems, you can set the limit on a per-service basis in
       inetd.conf, by changing "nowait" to "nowait.10000".
