HttpClient (Windows.Web.Http) stop automatic retry.

Question

Hello, is it possible to prevent HttpClient from retrying to send a request after receiving 401 response? Is there some kind of retry policy filter that can be used?

Answer 1

You should be able to do so by simply disabling HttpBaseProtocolFilter.AllowUI and not setting any HttpBaseProtocolFilter.ServerCredential.

HttpBaseProtocolFilter filter = new HttpBaseProtocolFilter();
filter.AllowUI = false;
HttpClient client = new HttpClient(filter);
var response = await client.GetAsync(uri);
Debug.WriteLine(response);

Thank you very much - it worked. I was aware of "AllowUI" property but description in HttpBaseProtocolFilter class reference says:

"Get or set a value that indicates whether the HttpBaseProtocolFilter can prompt for user credentials when requested by the server." 

That's why I didn't think setting it to true would help in my case. Anyway thanks for your very fast reply!
