BlackBerry Push Development

ERROR HttpPushWorker [] - Push Failed The remote server returned an error: (407) Proxy Authentication Required. Exception: System.Net.WebException

When attempting a server side push from a .Net application, an error 407 Authentication Required Exception is returned. 


Some machines are setup behind a proxy server and require authentication. The proxy object within your push application does not inherently supply the credentials of the currently logged in user and therefore the proxy refuses access. 


Add the below element to your .config file 

    <defaultProxy useDefaultCredentials="true"> </defaultProxy>


Within your code, Obtain the proxy of your default browser and assign default credentials of the current logged in user before making your HTTPWebResponse Call.


IWebProxy myProxy = myWebRequest.Proxy;

                    if (myProxy != null)


                        myProxy.Credentials = CredentialCache.DefaultCredentials;
