SSL_CTX_add_session(3)			     OpenSSL			   SSL_CTX_add_session(3)

       SSL_CTX_add_session, SSL_add_session, SSL_CTX_remove_session, SSL_remove_session - manipu-
       late session cache

	#include <openssl/ssl.h>

	int SSL_CTX_add_session(SSL_CTX *ctx, SSL_SESSION *c);
	int SSL_add_session(SSL_CTX *ctx, SSL_SESSION *c);

	int SSL_CTX_remove_session(SSL_CTX *ctx, SSL_SESSION *c);
	int SSL_remove_session(SSL_CTX *ctx, SSL_SESSION *c);

       SSL_CTX_add_session() adds the session c to the context ctx. The reference count for ses-
       sion c is incremented by 1. If a session with the same session id already exists, the old
       session is removed by calling SSL_SESSION_free(3).

       SSL_CTX_remove_session() removes the session c from the context ctx.  SSL_SESSION_free(3)
       is called once for c.

       SSL_add_session() and SSL_remove_session() are synonyms for their SSL_CTX_*() counter-

       When adding a new session to the internal session cache, it is examined whether a session
       with the same session id already exists. In this case it is assumed that both sessions are
       identical. If the same session is stored in a different SSL_SESSION object, The old ses-
       sion is removed and replaced by the new session. If the session is actually identical (the
       SSL_SESSION object is identical), SSL_CTX_add_session() is a no-op, and the return value
       is 0.

       If a server SSL_CTX is configured with the SSL_SESS_CACHE_NO_INTERNAL_STORE flag then the
       internal cache will not be populated automatically by new sessions negotiated by the
       SSL/TLS implementation, even though the internal cache will be searched automatically for
       session-resume requests (the latter can be surpressed by SSL_SESS_CACHE_NO_INTER-
       NAL_LOOKUP). So the application can use SSL_CTX_add_session() directly to have full con-
       trol over the sessions that can be resumed if desired.

       The following values are returned by all functions:

	    The operation failed. In case of the add operation, it was tried to add
	    the same (identical) session twice. In case of the remove operation, the
	    session was not found in the cache.

	    The operation succeeded.
