In fact a a very recent project my problem was that I misread the 
Synapse Docu and assumed that with a new HTTPMethod() call the send 
buffer ("document") would be clear. But on the contrary the send buffer 
is filled with the latest received document. This in fact leads to 
programs that mostly work but are due to very peculiar problems, as the 
target  HTTPserver might overrun and timeout ow whatever when bombed 
with huge request frames.

I don't think this is very hand, but I asked the software creators and 
it's a feature not a bug.

Thus before using HTTPMethod() of an instance of THTTPSend a second 
time, you to always need to clear the document buffer before.
