Background

HTTP is the application-layer protocol that most web pages are transferred with. HTTP keep-alive connections can be re-used for multiple requests, as opposed to non-keep-alive connections, which are limited to one request. Using keep-alive connections improves performance. This preference determines how long keep-alive connections are kept alive.

Possible values and their effects

Amount of time in seconds to keep keep-alive connections alive. Default: 115 seconds.

Caveats

  • This preference only has an effect if network.http.keep-alive is true.
  • Setting this to more than 115 probably won't help and will make things worse. (See the discussion page.)
