REST API app can have all requests filtered out

[SergeyKanzhelev]

Reported by the customer:

What I notice when running locally, the request fails it contains the response code but when its successful then it doesn’t I am not sure why?

This is RESTApi Project created using Visual Studio template for Azure Cloud Service -> WebRole -> Empty (Web API Check box) targeting .NET 4.5.2. Project just contain REST Endpoints there is no MVC used. Application Insights configured using Visual Studio (right click on the project and select add AI).

Removing filters from the collection helped to resolve the issue:

<Add Type="Microsoft.ApplicationInsights.Web.RequestTrackingTelemetryModule, Microsoft.AI.Web">
  <Handlers>
<!-- 
        Add entries here to filter out additional handlers: 

        NOTE: handler configuration will be lost upon NuGet upgrade.

     Remove handlers below:
-->
     <Add>System.Web.Handlers.TransferRequestHandler</Add>
     <Add>Microsoft.VisualStudio.Web.PageInspector.Runtime.Tracing.RequestDataHttpHandler</Add>
     <Add>System.Web.StaticFileHandler</Add>
     <Add>System.Web.Handlers.AssemblyResourceLoader</Add>
     <Add>System.Web.Optimization.BundleHandler</Add>
     <Add>System.Web.Script.Services.ScriptHandlerFactory</Add>
     <Add>System.Web.Handlers.TraceHandler</Add>
     <Add>System.Web.Services.Discovery.DiscoveryRequestHandler</Add>
     <Add>System.Web.HttpDebugHandler</Add>
    </Handlers>
</Add>

BTW, this issue may be a continuation of this one: #16

I was having the same issue, and also saw that commenting out the one line in the ApplicationInsights.config caused successful requests to start getting logged. Web API 2 project.

        <!--<Add>System.Web.Handlers.TransferRequestHandler</Add>-->

Not reproed. With the default AI Config I am getting all (sucess,failed) requests in WebApi project.

Tried both empty ASP.NET with WebAPI, and AzureCloudService project - both working fine.

Couple ideas:

• Maybe try running an app in IIS Here is how TransferRequestHandler used
• I believe we are filtering it so WCF requests wouldn't be reported twice. You can try running functional tests without it to confirm.
