Steps to reproduce
This is a PS 5.1 vs PS 7.1.4 behavior
I am trying to get information from the Web. When you submit the form data to the site, it sends to you a site that returns many different 30x codes including 308, 302 and 301. In PS 5.1 I had to work around this by erroring silently and manually picking up the next URL and continue this until I get to the final page. The same code will not work in PS 7.1.4. PS 7.1.4 Errors and never sets the response object information with:
Invoke-RestMethod: Object moved
Object moved to here.
I did adjust for the differences between the two concerning -MaximumRedirection values (I tried with both zero and non-zero in PS 7.1.4, 0 only works in PS 5.1)
Maybe my problem is with -MaximumRedirection, not sure. It would be nice if -MaximumRedirection actually worked and followed to the final site, but that didnt work in PS 5.1 either.
