Hey Steffen,
2 comments from a quick read and test (not yet comprehensive).

* I see that the HTTP_REFERER is now being used with the GPvar for 
referer is not set. It doesn't appear that this was the case before so I 
wonder about including what appears to be a small feature and change of 
behavior in 4.2.

* When should I expect the referer redirect to work with respect to 
caching? From my quick tests, it only worked if I marked the page as 
uncached.

Thanks,
Jeff
