Background
HTTP is the application-layer protocol that most web pages are transferred with. In HTTP 1.1, multiple requests can be sent before any responses are received. This is known as pipelining. Pipelining reduces network load and can reduce page loading times over high-latency connections, but not all servers support it. Some servers may even behave incorrectly if they receive pipelined requests. If a proxy server is not configured, this preference controls whether to attempt to use pipelining.
Possible values and their effects
true
Attempt to use pipelining in HTTP 1.1 connections.
false
Never use pipelining. (Default)
Caveats
- This preference has an effect only if you are not using a proxy. If you are using a proxy, see network.http.proxy.pipelining.
- network.http.keep-alive must be set to true for pipelining to work.
- network.http.version must be set to 1.1 for pipelining to work.
- Although this preference may improve performance, it may cause problems loading pages from some servers.
Recommended settings
Users who want better page loading speed can try setting this preference to true, keeping in mind this may break some websites.
