AW: AW: [squid-users] reverse-proxy for multiple domains

hi,

i guess i mixed something up or my english is not as good as it shut be. i
read this manual http://squid.visolve.com/white_papers/reverseproxy.htm#ee
and thought: "this is what you need."

we got two webservers an differnet ports and of course different ip's.
i wannted to put a reverse-proxyx in front of them to cache some requests
but i think this is nor what i mentionted in the postings so far?

regards
martin
