1. I read that squid will normally cache based on the relevant http cache headers. Is it possible to force a cgi script to be cached if it doesn't have these headers? i.e. if uri matches regex cache it no matter what.
You can use the refresh_pattern directive to tweak the level of caching, and even override certain HTTP rules if you like.
2. We are doing basic authentication with the apache module mod_auth_pgsql. This authentication against postgresql is resulting in a lot of database activity. I read somewhere that squid will cache authentication credentials. Does this work in reverse proxy mode?
Yes, if you do the authentication on the reverse proxy.
3. In a very old post (http://www.squid-cache.org/mail-archive/squid-users/199904/0174.html) I read:
"Squid is mainly a HTTP proxy server. The accelerator mode is a bonus, but I would not say that Squid is a very good or even fast HTTP server accelerator. "
Sounds like me..
Has this changed since 1999?
Not really no.
If not what are the other more robust reverse proxy servers out there?
Squid is very robust, and does a good job of it. It is just not lightingly fast and for plain file delivery most modern webservers can outperform Squid.
But if your server is not just delivering plain files or slow due to having heavy database operations or other things using a reverse proxy such as Squid can improve the situation significantly, and even more so if the resulting content is cacheable.
