The SSLTransport wraps an existing socket and establishes an SSL connection.
|
|
Contrary to Python's implementation of SSLSocket, it allows you to chain
|
multiple TLS connections together. It's particularly useful if you need to
|
implement TLS within TLS.
|
|
The class supports most of the socket API operations.

Raises a ProxySchemeUnsupported if the provided ssl_context can't be used
|
for TLS in TLS.
|
|
The only requirement is that the ssl_context provides the 'wrap_bio'
|
methods.

Python's httpclient uses makefile and buffered io when reading HTTP
|
messages and we need to support it.
|
|
This is unfortunately a copy and paste of socket.py makefile with small
|
changes to point to the socket directly.
