Best to wind down this thread. HTTP has a "Content-Length:" header or alternatively supports Chunked transfers. You're right that it's not OpenSSL-specific, but the general topic of "how do you design protocols atop TLS" and "how do you take a TCP protocol and put it on top of TLS" seem relevant. Huh. Looking closely, I see that HTTP requires header-based framing information when the request has a body - either Content-Length or Transfer-Encoding. And here I thought I had a pretty decent understanding of basic HTTP. Maybe I've just never hand-crafted a POST request. I learn something new every day. -- Jordan Brown, Oracle Solaris |
