This worked great, thanks.  I had the apache.conf stuff set (I am on  
FreeBSD and each customer has their own apache but I am familiar with  
how it is set up and so could translate from what you said).  I had the  
username and password directives there already but did not know the  
magic incantation in the URL to get it to work...

The docs state that with 5, WOAdaptorInfo was no longer a magic  
incantation but was made to be, upon configuration, in the app not  
found response.  But that did not make sense.

from
<http://developer.apple.com/documentation/LegacyTechnologies/ 
WebObjects/WebObjects_5.1/DeploymentAdditions/adaptors.html>

"WOAdaptorInfo page

The WebObjects 4.5 adaptor includes support for a page which displays  
information about the adaptor's current status. In WebObjects 4.5 this  
page was commonly known as the "xyzzy" page. In WebObjects 5 this page  
is referred to as the WOAdaptorInfo page. Furthermore, it is no longer  
returned by a "magic" request to the adaptor. Instead, if the  
WOAdaptorInfo page is enabled it is returned when a request does not  
specify an application or specifies an unknown application. (The  
WOAdaptorInfo page is disabled by default.) Finally, the content of the  
WOAdaptorInfo page has been modified to be more readable, and to  
include hyperlinks to connect to all known instances (either using  
Direct Connect or through the web server).

For the CGI adaptor, some environment variable names have changed  
between WebObjects 4.5 and WebObjects 5. The environment variable  
"WO_XYZZY_USERNAME" has been renamed "WO_ADAPTOR_INFO_USERNAME", and  
the environment variable "WO_XYZZY_PASSWORD" has been renamed  
"WO_ADAPTOR_INFO_PASSWORD".

The WOAdaptorInfo page displays all application and instance settings  
in the configuration. Additionally, the WOAdaptorInfo page displays the  
following statistics for each instance:
	• 	active reqs - The number of requests currently being serviced. This  
is the number of requests which have been sent to the instance for  
which the adaptor has not yet received a response (or timed out).
	• 	served - The total number of requests serviced by the instance.
	• 	conn pool peak - The peak number of connections to the instance in  
any single adaptor process. (Typically this is 1 for Apache or CGI.)
	• 	conn pool reused - The number of times a pooled connection to the  
instance has been reused.
	• 	refusing timeout - The amount of time (in seconds) the adaptor will  
wait before the load balancing can select the instance. This timer gets  
set to a nonzero value if the adaptor receives a response from an  
instance indicating the instance is refusing new sessions.
	• 	dead timeout - If this time is nonzero it indicates a  
communications failure has occurred with the instance. The timer is  
initialized with the configured dead interval for the application. The  
dead timeout indicates the remaining time from the dead interval. "

Thanks

happy now
