[Exist-open] httpclient

[Wolfgang F. <fr...@gm...>]

I am trying to write a POST request to a server. I do get a response but 
it is clear that the server was not able to read the parameters I 
posted.  The documentation is silent on what format the payload needs to 
be.  In the mailing list I only found examples that used variables, 
which doesn't help.

Could someone please enlighten me on the payload format?

Thanks in advance,
Wolfgang
