That's my experience as well and the only reliable

Hi Arno,
Just confirming that you meant to write:
ClientCnx-Receive(Junk, sizeof(Junk));
Instead of:
ClientCnx-Receive(Junk, sizeof(Junk));

Keith.
Here's my current code... As per your suggested code.

Dear All,
I have recently written a small Web Server application using the THttpServer

It serves GET requests perfectly, but when I added POST functionality,
(following the WebServ example) it has started generating EAccessViolations.
