title: getting "remote server cannot be resolved" on localhost does not get fixed by defaultProxy?
body: <p>here is the sitution, i am testing on my localhost from my machine at home (no proxy server and windows default firewall) and retrieving api.flickr.com xml file, when I come to work (that uses an ISA server to connect) I get "remote server could not be resolved" so I added these lines to the web.config</p>
  
  <pre><code>&lt;system.net&gt;
    &lt;defaultProxy&gt;
     &lt;proxy
      usesystemdefault="False"
      proxyaddress="http://localhost"
      bypassonlocal="True"
       /&gt;
     &lt;bypasslist&gt;
      &lt;add address="[a-z]+\.flickr\.com\.+" /&gt;
     &lt;/bypasslist&gt;
  
    &lt;/defaultProxy&gt;
   &lt;/system.net&gt;
  </code></pre>
  
  <p>that returns:<strong>System.Net.WebException: The remote server returned an error: (404) Not Found</strong>.
  what went wrong? thanks</p>
