Tech:Page names ending with a period confuse caching
If a page ends in a period is it a different page but pages with and without periods get confused when they are cached but not when Index.php is used. For example: Compare en:User:Mark. which has a following period and is not en:User:Mark even though the same page is displayed. The en:User:Mark page is actually here , not here .
