<DirectoryMatch> and </DirectoryMatch> are used to enclose a group of directives which will apply only to the named directory and sub-directories of that directory, the same as <Directory>. However, it takes as an argument a regular expression. For example:
<DirectoryMatch "^/www/.*/\[0-9\]\\{3\\}">
would match directories in /www/ that consisted of three numbers.
See Also:
<Directory> for a description of how regular expressions
are mixed in with normal <Directory>s.
