Jmeter 5.6x has issues with DotNetNuke site.

[osieber]

Expected behavior

Jmeter should post and redirect to the next page flow in DotNet Nuke. This works with Jmeter 5.5 but not in 5.6.x.

Actual behavior

We authored our load tests with Jmeter version 5.5. We used the build it recorder and the tests had no issues recording or executing. THis is a site built off of DotNetNuke. The page loads but when you hit any submit button (post to the webserver) it just drops to the same page. It does not redirect ot the next page as expected. There does not appear to be errors in the logs from what I can see.

THis happens with the test and when I use the recorder to make a new test.

Steps to reproduce the problem

1. start a new recorder session
2. navigate to this page: osieber.ejoinmestage.org/MyPages/RegistrationPageCopy/tabid/1396224/Default.aspx
3. Add any amount in the field
4. hit the Next button. At this point, the page just reloads instead of navigating to the next page.

This works without issues with 5.5, but any version of 5.6 it doesn't.
