It's possible to create a wiki page with a "\" character in the title, so that the page cannot be accessed by the "short URL" method from http://www.mediawiki.org/wiki/Manual:Short_URL#Alias_directive, where Apache rewrites URLs as http://server/wiki/title_here. 1. In the search box, enter foo\bar and click Go. 2. You are offered to create the page foo\bar. Click the edit link and go to http://server/wiki/index.php?title=Foo%5Cbar&action=edit 3. Edit and click Save. 4. You are taken to the page http://server/wiki/Foo%5Cbar, which produces a 404 error. However, the page has been saved in the "page" table in the database. 5. The page is accessible as http://server/w/index.php?title=Foo%5Cbar.
May be an Apache 2.x-specific issue, as with the double-forward-slash problem. No such problem on Wikipedia, where we're using 1.3.x.
