title: Mapping URL Pattern to a Single RequestHandler in a WSGIApplication
body: <p>Is it possible to map a URL pattern (regular expression or some other mapping) to a single RequestHandler?  If so how can I accomplish this?</p>
  
  <p>Ideally I'd like to do something like this:</p>
  
  <pre><code>application=WSGIApplication([('/*',MyRequestHandler),])
  </code></pre>
  
  <p>So that MyRequestHandler handles all requests made. Note that I'm working on a proof of concept app where by definition I won't know all URLs that will be coming to the domain.  Also note that I'm doing this on Google App Engine if that matters.</p>
