title: HttpWebRequest has no close method?
body: <p>I am very surprised to see <code>HttpWebRequest</code> has no close method, but its counter-part <code>HttpWebResponse</code> has. It makes me a little bit confused and inconvenient. :-)</p>
  
  <p>So, we only need to call Close on response and no need to treat with request? My concern is about leaks and better resource usage efficiency. I am using VSTS2008 + C# + .Net 3.5.</p>
