Maintains a map of HTTP request handlers keyed by a request URI pattern.


Patterns may have three formats:

  
*
  
*&lt;uri&gt;
  
&lt;uri&gt;*


 This class can be used to resolve an instance of HttpRequestHandler matching a particular request URI. Usually the resolved request handler will be used to process the request with the specified request URI.
