Hi markus, just FYI, it didn't work for me with the first https url 
also. There are some problems when viewing pdfs in-browser comes into 
play. IIRC byterange serving may be involved, see the thread at
http://aspn.activestate.com/ASPN/Mail/Message/zope-List/683104
for instance (the acrobat plugin).
Note that this also concerns some braindead commercial SOHO proxies, not 
only zope, but this is not the case here (we have no such beast, 
unfortunately some of our clients ;-().

Are you using PCGI of FCGI?

cheers,
