Web Proxies

Today, a problem emerged when internal LAN users connect to http://xxx.xxx.xxx/xxx. They all get a blank page. I was able to trace this a badly configured proxy in another part of our network.

After deciding on several options, I decided to use our own proxy connected to our own gateway. Several questions came up, among which are:

1) How do you force a squid proxy to use a certain parent cache for a certain domain?

example answer: cache_peer_domain 172.16.1.57 .co.in
(see http://wiki.squid-cache.org/CategoryConfigExample)

2) How about making sure that requests for certail URL goes direct, instead of querying the cache:

ACL foo dstdomain .example.net
Always_Direct Allow foo

3)If you want to configure Apache as a proxy, use this as reference: http://httpd.apache.org/docs/2.2/mod/mod_proxy.html. Apache can be configured in both a forward and reverse proxy (also known as gateway) mode

These and other administrative functions occupied my day today...
