title: Standard way to specify filename with HTTP PUT
body: <p>With HTTP PUT requests, is it typical for the filename to be included as part of the request URI such as:</p>
  
  <pre><code>http://host/myfilename.txt
  </code></pre>
  
  <p>or is it included as a standard header key/value pair? If so, what is the key?</p>
  
  <p>Thanks</p>
