I'm having this exact same problem and it's driving me mad. Everything is configured properly, everything works; I see the cache preload, etc. but I never see the request to the initialization page. It's my understanding this fake request should appear in
the IIS log.
I thought I had been on to something with SSL being the issue, since the application itself will try to redirect http to https. I tried implementing a rewrite rule as outlined here;
https://support.microsoft.com/en-us/kb/2843964 , and it seems to allow me to open the initialization page locally on port 80 and stays there without redirecting but I STILL never see the call to the
specified initialization page.
Does anyone have any pointers on where to look to troubleshoot this more? I also turned on FRT, and can see this happening in those logs; (Note, obscuring some info for security reasons, X'd out part IS the correct path to the page). Oddly, I don't see the
actual page name (default.aspx) in the URL here;
User-Agent: IIS Application Initialization Preload
The operation completed successfully.
This suggests it's working sort of, but that page still takes forever to load which indicates it really ISN'T being warmed up??...Ready to pull my hair out!
