Your problem is probably that your server reads data until the
connection is closed/blocked by the client as a sign that the full
request has been sent. However in never versions of Netscape they have
implemented the "Keep-Alive" header for multiple requests over a single
tcp/ip connection.
Instead of reading until the end of the connection you should find the
"Content-Length" header which tells you the size of the POST'ed data.
Read this number of bytes after the 2 CRLF's.
