How to Install PWA in the Backend

I'm testing on iOS 12.1.1.

The PWA installed at works perfect.

I would like to make one to work that way.

I compiled and installed the PWACalculator sample. I installed on Windows IIS and CentOS with Apache.

- In IIS the screen does not fill up. Using HTTPS.
"The logo does not appear at all. No HTTPS.

I could provide an example and pass the stones path to install on Windows and Linux.

For a PWA to be recognized, it needs to be accessed via HTTPS and there needs to be HTTP to HTTPS redirection.

Other than this, check  out with the Lighthouse tool to see if there might other things wrong
