+=head1 WARNINGS
+
+If a session-remove callback is set (SSL_CTX_sess_set_remove_cb()), this
+callback will be called for each session being freed from B<ctx>'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(B<ctx>, NULL) prior to calling SSL_CTX_free().
