Subject [PATCH] SSL not sending close alert message
Date Mon, 23 Feb 2004 21:22:05 GMT
Hi,
	I started working on Justin's idea of creating a EOC bucket - to do a SSL shutdown before
the socket close(). But since the ap_flush_conn is called just before closing the socket -
I thought of doing the SSL shutdown during the flush itself. Let me know what you think of
this patch.
