|
|
|
<p>SSL_set_session() sets <b>session</b> to be used when the TLS/SSL connection is to be established. SSL_set_session() is only useful for TLS/SSL clients. When the session is set, the reference count of <b>session</b> is incremented by 1. If the session is not reused, the reference count is decremented again during SSL_connect(). Whether the session was reused can be queried with the <a href="../man3/SSL_session_reused.html">SSL_session_reused(3)</a> call.</p>
|
|
|
|
<p>If there is already a session set inside <b>ssl</b> (because it was set with SSL_set_session() before or because the same <b>ssl</b> was already used for a connection), SSL_SESSION_free() will be called for that session. This is also the case when <b>session</b> is a NULL pointer. If that old session is still <b>open</b>, it is considered bad and will be removed from the session cache (if used). A session is considered open, if <a href="../man3/SSL_shutdown.html">SSL_shutdown(3)</a> was not called for the connection (or at least <a href="../man3/SSL_set_shutdown.html">SSL_set_shutdown(3)</a> was used to set the SSL_SENT_SHUTDOWN state).</p>

|
<p>SSL_SESSION objects keep internal link information about the session cache list, when being inserted into one SSL_CTX object's session cache. One SSL_SESSION object, regardless of its reference count, must therefore only be used with one SSL_CTX object (and the SSL objects created from this SSL_CTX object).</p>
