Hello Ebta,
thx for your reply. I tried many options with output_buffering and other things, nothing worked. At last, I assume my firewall or virus scanner operated by our corporate IT blocks the communication. On a linux system with the webserver and client running on the same machine (as intended on the target system) it runs fine!
