If your proprietary protocol truly runs "on top of HTTPS", then you'll have
no problem at all. Just do your GET/POST/WHATEVER operations like normal,
and libcurl will handle it fine. If your protocol doesn't actually use HTTPS
but rather a variant that only vaguely looks close enough to HTTPS to get
through some proxy servers, then you might have a problem.

This makes it sound like your protocol falls into the "only superficially
similar to HTTPS" category. If it were truly HTTPS, then you would set up
a POST (or PUT) transfer, send the data to the server from the
READFUNCTION then save the response through the WRITEFUNCTION.

It really depends on the protocol. If it's on top of HTTPS, then libcurl can
do it all. If it's just designed in such a way that CONNECT_ONLY
can get establish the connection, then you should be able to start using
curl_easy_send/recv to bang arbitrary encrypted data out and receive
responses.
