If you need to configure a website to access a webservice etc. which is deployed on another machine vie a proxy, you just need to update your web projects web.config file as shown below: < configuration >   ...   <!-- <system.net>     <defaultProxy useDefaultCredentials="true">       <proxy proxyaddress="http://proxyIPAdress:portNumber" usesystemdefault="True"/>     </defaultProxy>   </system.net> -->   ... </ configuration > That's all.  Happy coding :)
