Since persistent connections applies to only one transport link, it is important that proxy servers correctly signal persistent/or-non-persistent connections separately with its clients and the origin servers (or to other proxy servers). From a HTTP client or server's perspective, as far as persis...
HTTP can use two types of connections, which are . A. persistent and non-persistent connection B. connection with pipelining and without pipelining C. TCP and UDP D. parallel and serial connection 相关知识点: 试题来源: 解析 A persistent and non-persistent connection ...
The original HTTP specification always uses non-persistent connections; HTTP/1.1 added persistence because it is more efficient for web pages that embed a lot of external objects (which were rare when HTTP/1.0 was written.) However, even though HTTP/1.1 allows persistent connections there are impl...
I think the problem with the first img is (as you said) multiple objects seem to be sent with one connection ( 2 RTT). That is exactly definiton of a persistent connection. You'll send multiple objects and at the end you will close ( not given in the img). Your first drawing is m...

establishment, keep the connections in a tuned state, and reduce the potential number of open connections. However, persistent connections need to be managed with care, or you may end up accumulating a large number of idle connections, consuming local resources and resources on remote clients and...
If you do this, be aware that it can cause problems with PUTs, POSTs and persistent connections, especially if the client uses pipelining. That said, it is no worse than on 1.1, and we understand that keeping your server running is quite important. To compile without the lingering_close()...
Thanks for your insight on comparing persistent and non-persistent HTTP connections. But you made a significant misstatement in your analysis and I’m offering some education here for you and others. You compared 7 seconds with 22 seconds and said it…more -- Reply See all responses ...
With HTTP/1.1 persistent connections, the problem arises that broken scripts could return a wrong Content-Length (there are more bytes sent than specified). Unfortunately, in some cases, this is not possible after a bad response, but only before the next one. So, the HTTP Client must be ab...
