hody, just found a new http accelerator, varnish, which criticize squid, e.g. Why bother with Varnish - why not use Squid? Varnish was written from the ground up to be a high performance caching reverse proxy. Squid is a forward proxy that can be configured as a reverse proxy. Besides - Squid is rather old and designed like computer programs where supposed to be designed in 1980. Please see ArchitectNotes for details. I am not familiar with the internal of squid in fact, anyone has any comments?
