SSL_CTX_add_session() adds the session c to the context ctx. The refer-
ence count for session c is incremented by 1. If a session with the
same session id already exists, the old session is removed by calling
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
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 session 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_INTER-
NAL_STORE flag then the internal cache will not be populated automati-
cally 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_INTERNAL_LOOKUP). So the application can use
SSL_CTX_add_session() directly to have full control 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.
