Fix?
Persistent HTTP
- in HTTP/1.0, add “Connection: Keep-Alive\r\n” header
- in HTTP/1.1, P-HTTP built in
Does it help?
- mostly for server-side reasons, not network efficiency
- allows pipelining of multiple requests on one connection
Does it hurt?
- how does a client know when document is returned?
- when does the connection get dropped?
- idle timeouts on server side
- client drops connections
- server needs to reclaim resources
