Hello, I am looking to utilize squid as a reverse proxy for a medium sized implementation that will need to scale to a lot of requests/sec (a lot is a relative/unknown term). I found this very informative thread: http://www.squid-cache.org/mail-archive/squid-users/200704/0089.html However, is clustering the OS the only way to provide a high availability (active/active or active/standby) solution? For example, with Red Hat Cluster Suite. Here is a rough drawing of my logic: Client --- > FW ---> Squid ---> Load Balancer ---> Webservers They already have expensive load balancers in place so they aren't going anywhere. Thanks for any insight!
