Asp.net WebAPI HTTP SERVER ERRORS - user breaks the connection

Question

I have a Web.Api project, and I deployed it to Azure Web Sites. Some times I see many HTTP SERVER ERRORS in dashboard.

Detailed Error Information: Module ManagedPipelineHandler Notification ExecuteRequestHandler Handler System.Web.Http.WebHost.HttpControllerHandler Error Code 0x800703e3 Requested URL http://test-server:80/api/Statistics/ShowStories Physical Path D:\home\site\wwwroot\api\Statistics\ShowStories Logon Method Anonymous Logon User Anonymous

I don't know how to fix it and why it happens.

UPDATE

I found what this happens because user breaks the internet connections, and my question in next: how to catch this problems, maybe create some custom exception handler, and logger this problems, what this 'http server errors' and not show to Azure dashboard?

Did you try enabling ASP.NET Tracing to see if any helpful details are logged? — Siva Gopal

See this question: ASP.NET Web API OperationCanceledException when browser cancels the request

I think that if you handle OperationCanceledException correctly, the error will not be logged.

I'm handling OperationCanceledException in a quite robust way, and I still see these errors once in a while. So I have a feeling that this is not the correct answer.
