[Chilli] Coova-Chilli Redirection Problem

[Peter Wagner]

Hello Xabier,

I created a tcpdump on the client but it shows the same behaviour. The device get's the redirect for orf.at 2 times, 
resets both streams in the middle of the chilli redirect response and then accepts the heisse.de redirect without
a problem.

Cheers,
Peter Wagner
