HTTP/1.1 supports pipelining - multiple related requests are written to a single TCP socket without waiting for the responses to come back i.e. the requests are done asynchronously in-parallel, instead of doing them sequentially as usual (see picture). Some Web clients such as Opera and Firefox with FasterFox plugin use HTTP pipelining. Assume that ProxySG Is deployed as a forward proxy listening on port 8080.
A
If an HTTP client tries to use pipelining, the use of proxy will break the HTTP protocol.
B
For those HTTP clients that use pipelining, the use of forward proxy would ensure faster response time compared to the clients that do not use pipelining.
