If a session-remove callback is set (\fISSL_CTX_sess_set_remove_cb()\fR), this

callback will be called for each session being freed from \fBctx\fR's

session cache. This implies, that all corresponding sessions from an

external session cache are removed as well. If this is not desired, the user

should explicitly unset the callback by calling

SSL_CTX_sess_set_remove_cb(\fBctx\fR, \s-1NULL\s0) prior to calling \fISSL_CTX_free()\fR.
