How to disable proxy server via web.config file

09/032010

I’m developing a simple ASP.NET page to consume an RSS feed, format and output the content. My default proxy requires authentication, so unless I supply proxy credentials or bypass the proxy altogether, I get a “407 Proxy Authentication Required” error.

Fortunately I can access the RSS feed URL directly without going through the proxy, so the solution is simple – I just need to instruct my application to ignore the default proxy settings by adding the following lines in my web.config file, within the <configuration> element:

  <system.net>
    <defaultProxy>
      <proxy usesystemdefault="False"/>
    </defaultProxy>
  </system.net>
