Azure Machine Learning Web Service and Extension

Hi all,

We have create a ML web service which hosted at Azure Cloud.  Since ML web service does not support CORS, we can't call it thru javascript inside browser.  So we would like to call the service in CSharp through Extension.  However, once the  request has made, it took a long time (about several minutes) then return error 502.

Same CSharp code on my local pc (as a console app), the response return almost instantly.

My question is why ML Web service call failed in Extension?  In the past, I had used Extension called Azure Blob service (for encryption) and it works just fine.  



Are you running in the cloud, or self-managed? Have you tried adding logging to your extension, so you can more easily determine where the time is being spent?
