As far as I'm aware they don't, but there is growing awareness of the
benefits of supporting more HTTP mechanisms like persistent connections,
pipelining, content encoding for compression (not so much transfer
encoding), ETag validation, etc., so maybe it'll spread to caching as well
eventually.

I'd also like to see delta encoding, but I imagine it'll be a while before
we see it in Perl ;) That would be very cool for apps like RSS, because it
would allow you to maintain a complete history of the feed on the server
without knocking items off of the end of the queue. Of course, it gets
ugly when the file is large and a new client comes along, or an old one
needs to resync, but it's fun to think about.
