Sorry Dniel,

Sorry for I couldn't provide another public URL to repeat the problem.

Actually, the URL I tried is some property software, and didn't found any
free ones easy to test.

  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, NULL);

for the code in the demo:

  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, NULL);
  curl_easy_perform(curl);

I need to transmit the data on the very connection for many times, because
of cookie. the cookie should be stored in the client and then the server
will response the client correctly. the client and server got some
agreement, when the client is up, it just need to told the server:"hi , I am
up, you just do anything you want",to act this purpose, the client should
post an empty packet to the server, and then the server will got control of
the connection, the empty post is just change the controler between the
client and server. When the server receive the empty post, if it did got
some action to try, it will send the request as a response to the client,
and the connection will go on.

so the packet follow should be, the client send some data to the server to
do a verificaiton, and when passed in the server part, the server will tell
the client to give the control to it, and then the client send an empty
post, the server got the control of the connection.

for I didn't found any software can act like the server, and I just found a
branded software in some occasion, so I just take the URL fo the server for
a test, maybe, I will wirte the server part after the client worked all
well.

Thank you for all your help. really appreciate..
