title: How can I get a path as a key in express?
body: <p>My current route lookup is <code>app.get('/s/:key', ...</code>, but there is a good reason to be able to get other keys passed in that same way.  It is possible that I'll require getting paths that way as well--so basically I want to capture <code>app.get('/s/:key/more/stuff/here/', ...</code> and be able to read key independently of the <code>/more/stuff/here</code> portion.  I don't have an issue with capturing the other parameters as an array of arguments and then concatenating them, but I don't know how to do that--I get 404s if I try to capture anything other than <code>/s/:key</code> with nothing following.</p>
  
  <p>Is there a way to do this?</p>
