Now i am testing to use libcurl 's methods to communicate with a http server (version:apache-1.3.28 mod_ssl-2.8.15 openssl-0.9.6h[engine]).
My test program is simplessl.c from curl-7.12.0 's docs/examples.

When i execute simplessl, the return value of curl_easy_perform() is 51 which means "peer's certificate wasn't ok".
I have already delete the line: //curl_easy_setopt(curl,CURLOPT_SSL_VERIFYPEER,1); so simplessl will not disconnect
if server's certificate is not validate. And I got the following information in Apache log as follows:

[18/Aug/2004 14:50:50 01764] [trace] OpenSSL: Read: SSL negotiation finished successfully
[18/Aug/2004 14:50:50 01764] [debug] OpenSSL: write 29/29 bytes to BIO#008B3E00 [mem: 00968008] (BIO dump follows)

[18/Aug/2004 14:50:50 01764] [trace] OpenSSL: Write: SSL negotiation finished successfully
[18/Aug/2004 14:50:50 01764] [info] Connection to child 12 closed with standard shutdown (server 10.70.107.123:443, client 10.70.107.40)

So in my point of view, the SSL is ok.
My purpose is that after SSL connection is build, i want to send a message to HTTP Server with specified format and waiting for the response.
So i add "curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "name=daniel&project=curl"); " before curl_easy_perform() method be called. But I
can not capture this post package in the HTTP Server side. The Apache server seems receive nothing after SSL negotiation finished and close
the connection.

Why?
