203 \& int SSL_remove_session(SSL_CTX *ctx, SSL_SESSION *c);
206 \fISSL_CTX_add_session()\fR adds the session \fBc\fR to the context \fBctx\fR. The
207 reference count for session \fBc\fR is incremented by 1. If a session with
208 the same session id already exists, the old session is removed by calling
211 \fISSL_CTX_remove_session()\fR removes the session \fBc\fR from the context \fBctx\fR.
212 SSL_SESSION_free(3) is called once for \fBc\fR.
214 \fISSL_add_session()\fR and \fISSL_remove_session()\fR are synonyms for their
215 SSL_CTX_*() counterparts.
217 When adding a new session to the internal session cache, it is examined
218 whether a session with the same session id already exists. In this case
219 it is assumed that both sessions are identical. If the same session is
220 stored in a different SSL_SESSION object, The old session is
221 removed and replaced by the new session. If the session is actually
222 identical (the SSL_SESSION object is identical), \fISSL_CTX_add_session()\fR
223 is a no-op, and the return value is 0.
225 If a server SSL_CTX is configured with the SSL_SESS_CACHE_NO_INTERNAL_STORE
226 flag then the internal cache will not be populated automatically by new
227 sessions negotiated by the SSL/TLS implementation, even though the internal
228 cache will be searched automatically for session-resume requests (the
229 latter can be surpressed by SSL_SESS_CACHE_NO_INTERNAL_LOOKUP). So the
230 application can use \fISSL_CTX_add_session()\fR directly to have full control
231 over the sessions that can be resumed if desired.
233 The following values are returned by all functions:
237 \& The operation failed. In case of the add operation, it was tried to add
238 \& the same (identical) session twice. In case of the remove operation, the
239 \& session was not found in the cache.
