Details
The default value is 30 days (30 * 86400 seconds).
This means most MediaWiki cookies will last 30 days.
This includes login/session cookies when the "Keep me logged in (for up to $1 days)" option is not set. When "Keep me logged in (for up to $1 days)" is set, $wgExtendedLoginCookieExpiration is used instead (although by default that settings falls back to $wgCookieExpiration).
When "Keep me logged in (for up to $1 days)" is not set, login expiry is also limited by $wgObjectCacheSessionExpiry (the session expires when there is no interaction for that time span).
| MediaWiki version: | ≥ 1.22 |
Since MediaWiki 1.22 setting this configuration variable to 0 makes cookies session-only. This was previously documented as working, but broken.
This is used by WebResponse::setcookie and mw.cookie.set, though an individual cookie can have a custom expiration.
