mm do you mean the php bug is that it doesnt show the outgoing post fields?
coz im not so sure that curl can do that in the linux shell either? i guess
the content length being the same is a good indication that the data is the
same. furthermore when i use http i can view the postfields with my proxy.
its a roundabout solution but i'll accept it :P
thanks for all your help!
