Sometimes you may notice a strange caching behavior by the applications running in IIS. Today I found that my ASP.NET application showed a blank page. It is hosted on Windows Server 2019 in Azure Platform. I tried multiple times to resolve the issue but did not get success.

After searching about the issue, I found a suggestion in Google search to remove all ASP.NET temporary files. Once I removed all the temporary files, the application start working again.
