SSL_CTX_add_session(3)      OpenSSL      SSL_CTX_add_session(3)





NAME
       SSL_CTX_add_session, SSL_add_session,
       SSL_CTX_remove_session, SSL_remove_session - manipulate
       session cache

SYNOPSIS
        #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);

DESCRIPTION
       SSL_CTX_add_session() adds the session c to the context
       ctx. The reference 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_SES-
       SION_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_*() counterparts.

NOTES
       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 identi-
       cal), 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 ses-
       sions negotiated by the SSL/TLS implementation, even
       though the internal cache will be searched automatically
       for session-resume requests (the latter can be sur-
       pressed 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.

RETURN VALUES
       The following values are returned by all functions:

       o
            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.

       1
            The operation succeeded.
