Template:Page specific user rights extensions

The  category contains various extensions that attempt to restrict a user's access to specific pages based on the namespace, category links, and/or title patterns. Before installing one of these extensions, users should be aware that such extensions are likely to exhibit two significant problems:


 * caching problems: MediaWiki's page caching facilities do not currently support rights-specific caching. Any extension that tries to exclude or all of a page based on user rights is likely to result in performance declines (if caching is turned off) and/or security leaks when a page cached for a user with higher rights is viewed by a user with lesser rights.
 * multiple exit paths: Page content has many exit paths in MediaWiki: direct page views, excerpts inserted into search results, special pages, RSS feeds, and numerous extensions that read directly from the MediaWiki database. There is no one exit path that either the MediaWiki core or its extensions rely on.  Hence it is virtually impossible for any extension to provide full security.
