Summary: FOLLOWLOCATION and subsequent headers

Initial Comment:
The Server on the subsequent request via followlocation is waiting for extra data and hangs; as the Content-Type and Content-Length headers are included in the second request.

This isnt normal behaviour is it?!

My debug is in the below <snip>pets, aswell as another example found online. My debug has had the URLs changed by hand so there might be typos.

Message:
Can you please tell us exactly how to repeat this issue?

Are you possibly inserting those headers yourself?
