The problem only exists in Domino 8.x

HCL Notes/Domino 8.5 Forum (includes Notes Traveler)

Subject:

We are having the same issue with our web application, and yes, the previous poster is right: post data doesn't arrive to Domino HTTP. We also figured out that the same application works fine when running on Domino 7.0.4, so using Galaxy Nexus (Android 4.1) login form is working fine when accessed on Domino 7.0.4 HTTP and returns 'Invalid POST Request Exception' on Domino 8.5.3FP1.
Trying the same login form from desktop browser of from Google Chrome for Android also works fine.
So it looks like there is some issue between Android 3.x - 4.x and Domino HTTP 8.x.

Debug data is provided below:
