<p><a href="URLMap.html"><code>Rack::URLMap</code></a> takes a hash mapping urls or paths to apps, and dispatches accordingly.  Support for HTTP/1.1 host names exists if the URLs start with <code>http://</code> or <code>https://</code>.</p>

<p><a href="URLMap.html"><code>URLMap</code></a> modifies the SCRIPT_NAME and PATH_INFO such that the part relevant for dispatch is in the SCRIPT_NAME, and the rest in the PATH_INFO.  This should be taken care of when you need to reconstruct the URL in order to create links.</p>

<p><a href="URLMap.html"><code>URLMap</code></a> dispatches in such a way that the longest paths are tried first, since they are most specific.</p>
