152If a session-remove callback is set (\fISSL_CTX_sess_set_remove_cb()\fR), this
153callback will be called for each session being freed from \fBctx\fR's
154session cache. This implies, that all corresponding sessions from an
155external session cache are removed as well. If this is not desired, the user
156should explicitly unset the callback by calling
e056f0e0 157SSL_CTX_sess_set_remove_cb(\fBctx\fR, \s-1NULL\s0) prior to calling \fISSL_CTX_free()\fR.
