Re:Re: Re: SSL read error: 5 - What could be the reson?

Let's just say SSL support is not complete with Curl. I wrote a perl script to do the same and it always works. I am posting a message to a secure server and getting the response.
I glanced through the source code and I found that there was no support for servers that intiate authentication for sending response. Here is the quote from OpenSSL site (from the FAQ, item - 19):
"A pitfall to avoid: Don't assume that SSL_read() will just read from the underlying transport or that SSL_write() will just write to it -- it is also possible that SSL_write() cannot do any useful work until there is data to read, or that SSL_read() cannot do anything until it is possible to send data. One reason for this is that the peer may request a new TLS/SSL handshake at any time during the protocol, requiring a bi-directional message exchange; both SSL_read() and SSL_write() will try to continue any pending handshake. "
I guess the server I am trying to post the message to, is an exception they are referring to. My posted message reaches the server but I don't get the response.
I didn't find the call "SSL_set_accept_state()" in the Curl source code. So Curl doesn't seem to understand the request for a new TLS/SSL handshake before the secure server sends the response. Curl uses the same handle for both SSL read and SSL write calls.
Where as Perl uses the same OpenSSL but their modules are coded to handle this situation. So I gave up on Curl and embedded perl interpreter in my C++ code.
