HTTP pipelining (translated as HTTP pipelining ) is a technology that allows you to send multiple requests to the server at once in one connection, without waiting for corresponding responses. Pipelining is only supported in HTTP / 1.1, but not in 1.0.
Microsoft Internet Explorer does not support HTTP pipelining, and it is disabled by default in Mozilla Firefox .
Positive Action
Enabling HTTP pipelining should increase the speed of loading pages on slow channels and reduce the number of TCP / IP packets, i.e. the network load. Pipelining will benefit most from those whose response time is a significant part of the total connection time (this is satellite Internet , DSL and Dial-Up ).
Negative action
Pipelining significantly increases the load on the server, which can lead to DoS . Therefore use by users unfamiliar with the principles of pipelining [by whom? ] (for example, using Fasterfox for Firefox) is not recommended.
Since the server must give the answers in exactly the same sequence as the requests were received, one slowed down request slows down all subsequent ones in the “packet”. This will not happen when static is returned - but it is already cached.
