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 page loading times, but not all servers support it. Some servers may even behave strangely 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.

true

Never use pipelining. (Default)

Caveats

  • This preference only has an effect 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.
  • While this preference will 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.
