Hi guys, We want to replace our current proxy solution (crappy commercial product which is way too expensive) and thought about Squid, which is a great product.I already found a couple of example configurations, basically for reverse proxying. What we are looking for is a caching and authentication (LDAP and NTLM) only solution with content filtering via ICAP. We have following configuration in mind (firewalls omitted): Clients | | v Loadbalancer | | v Squid-Proxies <----> ICAP-Server | | v INTERNET We are expecting approx. 4500 requests per second average (top 6000 RPS) and 150Mbit/s, so I suppose we need a couple of Squids. The preferable solution would be big servers with a lot of memory and Squid 3.0 on a 64Bit RHEL5. Does anybody know any similar scenarios? Any suggestions? What are your experiences? The ICAP Servers are commercial ones (at least at the beginning), but I have following problem. I want to use multiple ICAP Servers in each Squid configuration with loadbalancing, unfortunately it is not supported and does not work in Squid 3. best regards
