Browser.cache.check doc frequency - MozillaZine Knowledge Base (original) (raw)

Background

When a page is loaded, it is cached so it doesn't need to be downloaded to be redisplayed. If the page changes after a previous visit, you may want to redownload it anyway to get the updated page. This preference controls how often to check for a newer version of a cached page.

Possible values and their effects

0

Check for a new version of a page once per session (a session starts when the first application window opens and ends when the last application window closes).

1

Check for a new version every time a page is loaded.

2

Never check for a new version - always load the page from cache.

3

Check for a new version when the page is out of date. (Default)
