A good web cache like Squid will do that -- as long as you configure
your server to send correct modified-since answers ...
I toyed with such a solution for a while (with a modified squid that
got recache instructions every time a resource was modified in the
content management system) but after seeing the performance we get
with the current system it wasn't worth the time (and extra administrative
complication that such a setup would generate - more components means
more possible points of failure). Our limiting factor seems to be the
number of parallel processes (and resources like file descriptors) -- 
i had to patch the kernel to fix that.
