how to configure squid server to cache for internet clients

[Maaz]

Hi Gurus
Os: rhel 3.0, rhl 9.0

firewall box external interface ip: 202.a.b.c
firewall box internal interface ip: 10.0.0.1
Squid server ip: 10.0.0.2
Apache server ip: 10.0.0.3

I have configure the apache server for virtual hosting(multiple websites are running on the same physical machine and on the single ip) successfully.

My firewall server(iptables), is configured to DNAT, i.e firewall box redirect/forwards all the http request to my webserver.

But I want my firewall box, that instead of forwarding the http request to my webserver, firewall box forwards every http request to my squid server, and my squid get the webpage from webserver and forwards/reply the page back to the firewall server. likewise if squid server already have done its job.. then any new request will be directly serve from squid cache.

Is it possible ? if yes HOW ?

My understanding was that squid cached content for your webusers looking out, not for content coming in.

I may be wrong, but this idea might not work. The documentation should be able to tell you weather it can work or not.

If possible, the squid users will tell you how.

What are the benefits you think you will achieve if this is possible?

Dear SEP, yes I want my squid server cache for internet clients.
The only benefit is that webserver receive a hit/request only when, the web content expires on the squid cache.

This implementation doesnt sounds me so good .. but my client was running MS ISA server for the same sake/pupose.
When configured for Web Publishing(i.e web servers are accessed via ISA)MS ISA server, also cache for internet clients, and this feature is called "Reverse Caching"

My clients want me to implement the Reverse Caching feature via squid.
