Windows 8 App - Proxy detection issue

Question

Hi All

I have a Windows 8 Application running behind the proxy and it throwing the exception "Proxy authentication required (407)."

Tried the solutions specified in the following thread, with no use

http://social.msdn.microsoft.com/Forums/en-US/winappswithcsharp/thread/64a8d24e-9b99-4cae-9e6c-ea1db05ef3a1

I am trying to read some RSS feed and display to the UI using the following Code snippet

SyndicationClient client=new SyndicationClient();
SyndicationFeed feed=await client.RetrieveFeedAsync(feedUri);

This Code passes and displays the information sometimes; but most of the times it failed with the Proxy exception.

How can I ask the user for authentication?

When we Open the built-in News App or Finance App, it is asking the User to enter Proxy details and connecting to internet. How can I achive the same? If the App fails to authenticate the proxy, prompt the user to enter details [like built-in apps] and once the suer enters the details, try to connect to internet using the entered details.

Thanks in Advance

Answer 1

You can use CredentialPicker then get ID and password by CredentialPickerResult

Once you get it, use CredentialCache to create an ICredential

CredentialCache myCache = new CredentialCache();

myCache.Add(new Uri("http://my-proxy:my-port"),"Basic",new NetworkCredential(ID,Password));

then assign to the handler credential:

handler.Proxy.Credentials = myCache;

If you have any further question, feel free to contact me

Thanks Emi Smith.

Proxy detection issue is resolved by enabling the "Internet (Client & Server)" capability. Earlier Internet (Client) was enabled.

Prompting the user for proxy credentials will be done using your suggestion.

Thanks

Where is this 'Capabilities' window found ?

You should double click on the file 'Package.appxmanifest' [for your main project] in the Solution Pane. Then click on 2nd tab.
