Recent Research in Web Caching

Caching on the world wide web has received a lot of attention lately. 
Several researchers and service providers have been looking at ways to 
improve caching to reduce user perceived latency, bandwidth usage, and 
server load. Several products are already on the market. Some of the 
changes to the HTTP protocol will improve the caching situation on the 
Web.

I will talk about some new ideas in web caching involving piggybacking 
of validation checks (to reduce future connections), server invalidations 
(to notify proxy of changes to resources on the server), end to end 
performance improvement (by grouping server resources and using 
proxy cache signatures) and (time permitting) server assisted 
cache replacement.
