I have setup a IIS web farm using Windows Server 2012 R2 Standard, IIS 8.5 with the following extensions: Web Farm Framework v1.1 External cache v1.0, URL Rewrite v2, ARR v3.
The URL Rewrite rules contain a rule mapping of "*" generated automatically upon the creation of the IIS web farm.
I tried to access http://localhost/some_random_name and the request was processed by the local IIS instead of my IIS web farm and it returns HTTP 404.
I turned on FailedRequestTracing logging and there was no logs captured. I presume this is because the local IIS has processed the request as HTTP 404 instead of routing to the IIS web farm.
How do I troubleshoot/debug this issue?
