Syntax: <FilesMatch regex> ... </FilesMatch>
Context: server config, virtual host, .htaccess
Status: core
Compatibility: only available in Apache 1.3 and above.

The <FilesMatch> directive provides for access control by filename, just as the <Files> directive does. However, it accepts a regular expression. For example:

   <FilesMatch "\\\\.(gif|jpe?g|png)\$">

would match most common Internet graphics formats.
