- HTTP/1.1 should reduce total number of TCP connections significantly - If style sheets become heavily used, many pages may go back to being a single document
- We should still see benefit from surfing to next page on the same web site
 
- Operating systems have been optimizing the TCP connection creation path; this will become less important for most (but not all) servers
- Will HTTP/1.1 cache control directives be exploited by Web site designers?
- Cache validation is MUCH cheaper - will this result in more aggressive cache validation and validation applications?- e.g. Laptop proxy caches, for road Warriors?  e.g. Revalidate 10000 items in their 1 gigabyte cache?
