Changelog
Daniel Stenberg (27 Mar 2008)
- As found out and reported by Dan Petitt, libcurl didn't show progress/call
the progress callback for the first (potentially huge) piece of body data
sent together with the POST request headers in the initial send().
Daniel Stenberg (25 Mar 2008)
- Made setting the CURLOPT_SSL_CTX_FUNCTION option return a failure in case
libcurl wasn't built to use OpenSSL as that is a prerequisite for this
