     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_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_*() 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 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_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:

               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.
