A very strange thing is happening on my site. When I go to a certain page I get a 404 error, but the file is definitely there. In fact when I open up the same page in incognito, the page loads without issue. What could be causing this?
This is an ASP.NET application on a Windows Server 2012, with IIS 8.5.
I checked the log files, and I'm not seeing any references to that request with the 404. I see a few that returned 200's, but nothing with a 404.
