160If a session-remove callback is set (\fISSL_CTX_sess_set_remove_cb()\fR), this
161callback will be called for each session being freed from \fBctx\fR's
162session cache. This implies, that all corresponding sessions from an
163external session cache are removed as well. If this is not desired, the user
164should explicitly unset the callback by calling
e056f0e0 165SSL_CTX_sess_set_remove_cb(\fBctx\fR, \s-1NULL\s0) prior to calling \fISSL_CTX_free()\fR.
