Caching Server

Can any one suggest me a caching server that can at least save some of my bw? i am using squid but it is not caching any dynamic contents.

what about a proxy?

i am already running squid proxy server. but it cannot cache dynamic site.

..which is kind of intended.

They are dynamic after all.
And if that content´s Expire header tells squid, that it is already old, then yes:
squid will not cache it.
