[contract gig] Squid cache expert needed!

Squid developers,
We would like to start using Squid-caches to take the load off of our
application and http servers. We need someone who has hands-on
experience setting up squid-cache clusters in a load balancing
environment. We also need a custom cache filter written to check for
the existence of a logged-in cookie, so that we only cache and serve
pages for non-logged in users. Our proposed setup looks like this:

internet
|
|
firewall & load balancer
|
|
+--Squid-cache 1
+--Squid-cache 2
|
|
+--App server 1
+--App server 2
|
|
+--DB server, etc.

I would like the Squid cache to also handle load balancing it's
requests to the App servers, but the only documentation I can find is
the setup Wikipedia had/has for it's servers. If this is not the case,
we could put another load balancer between the Squid & App servers,
although I'd rather not have the extra server.

"Squid cache servers used response time measurements to distribute
page requests between seven web servers."

We have not ordered our servers yet, so I'm also looking for
recommended server configurations for our two squid servers, ram, disk
space, etc. We will be ordering servers as soon as we have this
component of our solution worked out.

Please feel free to ask for more details or make suggestions based on
this information.

Thanks,
Cloude
