Synopsis
========

`#include <ts/ts.h>`

.. function:: void TSSslVConnReenable(TSVConn svc)

Description
===========

Reenable the SSL connection :arg:`svc`. If a plugin hook is called, ATS
processing on that connnection will not resume until this is invoked for that
connection.

If the server is running OpenSSL 1.0.1 with the appropraite patch installed or
it is running OpenSSL 1.0.2, the plugin writer can pause SSL handshake
processing by not reenabling the connection. Without the OpenSSL patch or
running an OpenSSL versions older than 1.0.2, the handshake processing in
``SSL_accept`` will not be stopped even if the SNI callback does not reenable
the connection.

Additional processing could reenable the virtual connection causing the
``SSL_accept`` to be called again to complete the handshake exchange.  In the
case of a blind tunnel conversion, the SSL handshake will never be completed by
Traffic Server.

This call does appropriate locking and scheduling, so it is safe to call from
another thread.
