Comment 13 for bug 1999909

Hey @johnfuqua, I try bio version, it doesn't work as well.

I borrow a piece of a bio code from [2], here's my complete bio test code [1].

Although my bio test did not succeed, I still believe that's because python's wrap_socket doesn't support tls-over-tls, so the idea in my mind is:

1, need to bypass wrap_socket and implement another wrap method (eg: wrap_ssl_socket) with openssl to be able to wrap ssl_socket instead of non-ssl socket, this seems very difficult.

2, or use a third-party solution, eg: pycurl, I'm not sure whether more third-party python libraries have implemented tls-over-tls feature.
