Hmmm...the FIN flag would mean the client aborted or tore down its TCP
connection, right? And probably that explains why the finished signal
is not emitted.

Could there be any other code path where you're aborting this request?

As for the double append, i have no clue. :/

Does this webserver support GET request for the same action (the one
you're trying to do with POST)? If it does, maybe you can check to see
if GET behaves properly.

HTH,
