Set proxy for WebRequest in web.config

Put this in web.config, you can set usesystemdefault but for me that dont work.

<system.net>
  <defaultproxy>
    <proxy
      usesystemdefault="false"
      proxyaddress="http://192.168.1.1:3128"
      bypassonlocal="true"
    </proxy>
  </defaultproxy>
</system.net>

Keys: asp.net, webrequest, proxy.
