Basic authentication
XWiki supports basic access authentication, a method designed to allow a Web browser, or other client program, to provide credentials - in the form of a user name and password - when making a request. You can get authentified against an XWiki server with the basicauth protocol using the following type of URL:
http://username:password@mywiki.xwiki.com/xwiki/bin/view/Main/WebHome?basicauth=1works
