Hello Jim,

Here is the current output from your server:
HTTP/1.1 200 OK
Date Wed, 06 Mar 2002 19:19:09 GMT
Server Apache/1.3.20 (Unix)
Keep-Alive timeout=15, max=100
Connection Keep-Alive
Transfer-Encoding chunked
Content-Type text/plain; charset=iso-8859-1
content-length 79



Here is what we are looking for:

HTTP/1.1 200 OK
Date Wed, 06 Mar 2002 19:17:44 GMT
Server Apache/1.3.20 (Unix)
X-DAS-Status 200
X-DAS-Version DAS/0.95
Keep-Alive timeout=15, max=100
Connection Keep-Alive
Transfer-Encoding chunked
Content-Type text/plain; charset=iso-8859-1
content-length 1037


	This will allow clients to know what version of the spec you are
supporting at an early stage and reduce the # of round trips we need to
make to figure this out.


				Thanks Jim!!
