161If a session-remove callback is set (\fISSL_CTX_sess_set_remove_cb()\fR), this
162callback will be called for each session being freed from \fBctx\fR's
163session cache. This implies, that all corresponding sessions from an
164external session cache are removed as well. If this is not desired, the user
165should explicitly unset the callback by calling
e056f0e0 166SSL_CTX_sess_set_remove_cb(\fBctx\fR, \s-1NULL\s0) prior to calling \fISSL_CTX_free()\fR.
