It might be possible, but this stuff looks very deep. You might have to dedicate yourself to C++ more than you might want to, and more than I would want to because I am on BASIC's side too much. Might have to use some function calls from there and figure out what is the library (file extension DLL or SO) to link with the QB64 program. Pay attention to the license for those libraries... this is a PITA with LGPL and those other variations.
This might be easiest on Windows through the API, if the libraries were written by Microsoft. Otherwise I'm naive enough to think this type of functionality would be available on Unix and descendants.
I almost forgot to mention that it might be possible, while the "HTTPS" functionality gets away from `$UNSTABLE` status. It could be tried first with the QB64 commands, but it's going to depend on the server response and how much it might require the dedicated library.
