-/**
- * Internet Explorer derives a cache filename from a URL, and then in certain
- * circumstances, uses the extension of the resulting file to determine the
- * content type of the data, ignoring the Content-Type header.
- *
- * This can be a problem, especially when non-HTML content is sent by MediaWiki,
- * and Internet Explorer interprets it as HTML, exposing an XSS vulnerability.
- *
- * Usually the script filename (e.g. api.php) is present in the URL, and this
- * makes Internet Explorer think the extension is a harmless script extension.
- * But Internet Explorer 6 and earlier allows the script extension to be
- * obscured by encoding the dot as "%2E".
- *
- * This class contains functions which help in detecting and dealing with this
- * situation.
- *
- * Checking the URL for a bad extension is somewhat complicated due to the fact
- * that CGI doesn't provide a standard method to determine the URL. Instead it
- * is necessary to pass a subset of $_SERVER variables, which we then attempt
- * to use to guess parts of the URL.

--- SQL to insert update keys into the initial tables after a

--- not have to run it by itself unless doing a manual install.
--- Insert keys here if either the unnecessary would cause heavy
--- processing or could potentially cause trouble by lowering field
--- sizes, adding constraints, etc.
--- When adjusting field sizes, it is recommended removing old
--- patches but to play safe, update keys should also inserted here.

--- The /*_*/ comments in this and other files are
