title: 404 - not found. But browser can read the url
body: <p>In my ASP.Net app, I open a request to a url as follows:</p>
  
  <pre><code>webRequest = WebRequest.Create(url);
  response = webRequest.GetResponse();
  </code></pre>
  
  <p>But the GetResponse returns an exception of:</p>
  
  <pre><code>The remote server returned an error: (404) Not Found.
  </code></pre>
  
  <p>The url does in fact exist. If I copy the url and enter it in my browser, it will show the page. What could be causing this exception?</p>
