155If a session-remove callback is set (\fISSL_CTX_sess_set_remove_cb()\fR), this
156callback will be called for each session being freed from \fBctx\fR's
157session cache. This implies, that all corresponding sessions from an
158external session cache are removed as well. If this is not desired, the user
159should explicitly unset the callback by calling
e056f0e0 160SSL_CTX_sess_set_remove_cb(\fBctx\fR, \s-1NULL\s0) prior to calling \fISSL_CTX_free()\fR.
