A redirect is a page that contains a line such as:
Such pages serve as "symbolic links" to their target page; in most contexts referring to the redirect page (linking to it, using it as a template, using it as a file name etc.) will have the same result as referring to the target page.
Redirects are recorded in the redirect table.
Configuration settings relevant to redirects include:
- $wgDebugRedirects (defaults to false), displays redirect location instead of actually redirecting to the target URL.
- $wgDisableHardRedirects (defaults to false), disables redirects to special pages and interwiki redirects, which use a 302 and have no "redirected from" link.
- $wgInvalidRedirectTargets (defaults to
array( 'Filepath', 'Mypage', 'Mytalk' )) is an array of invalid page redirect targets.
- $wgMaxRedirectLinksRetrieved (defaults to 500), is the maximum number of links to a redirect page listed on Special:Whatlinkshere/RedirectDestination.
- $wgMaxRedirects (defaults to 1), is the max number of redirects to follow when resolving redirects.
- $wgRedirectSources (defaults to false), is a regular expression to restrict URLs which will be displayed as 'redirected from' links.
