XML Sitemap Pattern searches are performed against the <a href="https://gist.github.com/jaswsinc/338b6eb03a36c048c26f" target="_blank">REQUEST_URI</a>. A wildcard <code>**</code> (double asterisk) can be used when necessary; e.g., <code>/sitemap**.xml</code>. Note that <code>**</code> = 0 or more characters of any kind, including <code>/</code> slashes. <code>*</code> (a single asterisk) means 0 or more characters that are NOT a slash <code>/</code>. Your patterns must match from beginning to end; i.e., the special chars: <code>^</code> (beginning of string) and <code>$</code> (end of the string) are always on for these patterns (i.e., applied internally). For that reason, if you want to match part of a URI, use <code>**</code> to match anything before and/or after the fragment you\'re searching for. For example, <code>**/sitemap**.xml</code> will match any URI containing <code>/sitemap</code> (anywhere), so long as the URI also ends with <code>.xml</code>. On the other hand, <code>/sitemap*.xml</code> will only match URIs that begin with <code>/sitemap</code>, and it will only match URIs ending in <code>.xml</code> in that immediate directory — bypassing any inside nested sub-directories.
