[Mono-list] Live switching from non-secure to SSL connection

[Antonello Provenzano]

Guys,

I would like to ask for an help understanding how to switch from a
non-secure to a SSL connection, during an active connection.
The problem is the following: I have to create a server service that
accepts connections from remote clients as non-secure by default.
After a connection is accepted, a check is done on the connection
properties setted by the user: between these properties there'd be a
flag (false=0, true=1) indicating if the connection must be under a
secure layer or not. If this flag is set to true, the connection
should be placed into a secure layer, otherwise it remains the same.

Is there any walkthrough to follow to implement such this task, or
anyone could provide me with an example code, eventually to extend, I
could reference to?

Thanks in advance.
Antonello
