Web Svr 6.1 SP4 App Svr 8.1 integration service-passthrough Working example

Question

This is a verbatim example from a working installation.
Pathnames etc will differ from this example.
This is an example of the integration of SUN Java System Web Server 6.1 SP 4 and
SUN Java System Application Server 8.1 2005Q1.
The scope of this integration is successfully accessing a working application
hosted on the application server by making HTTP requests to the web server.
Download and install the "Reverse Proxy Plug-in"
The "Sun Java System Web Server 6.1 Add-Ons" download from sun.com
includes the libpassthrough.so shared object.
libpassthrough.so includes the required passthrough Server Application Function(s) (SAF).
The output of the strings command on libpassthrough.so followed by a
grep for passthrough will list the available Server Application Function(s).
strings libpassthrough.so | grep -i passthrough
magnus.conf file edits.
/export/home/accesmanagerinstalldir/opt/SUNWwbsvr/https-menfi.houston.rr.com/config/magnus.conf
Add this line.
Init fn="load-modules" shlib="/export/home/accesmanagerinstalldir/opt/SUNWwbsvr/plugins/passthrough/libpassthrough.so"
obj.conf edits.
NameTrans fn="assign-name" from="/pwc(|/*)" name="passthrough"
Position of the NameTrans directive is significant.
The NameTrans directives are sequentially searched until a match is found.
One and only one NameTrans directive is utilized for the
NameTrans stage of each HTTP request.
My configuration had this directive as the first NameTrans directive of the obj.conf file.
<Object name="passthrough">
Service fn="service-passthrough" servers="http://192.168.1.199:8080"
</Object>
Once a NameTrans match is found the corresponding Object
within the obj.conf file is utilized.
In this example the name attribute of the NameTrans directive corresponds
to the name attribute of the Object.
The Service directive invokes the service-passthrough Server Application Function (SAF)
of the libpassthrough.so.
The servers argument is passed to the service-passthrough function.
HTTP requests made directly to the application server where the application is hosted
are sussessful. Note the 8080 port in the URL.
http://localhost:8080/pwc/PWCUnprotected
HTTP requests made to the WebServer are successful as well.
The requests are "passed through" between the Web Server
and the Application Server.
http://localhost:80/pwc/PWCUnprotected
http://localhost/pwc/PWCUnprotected
LOG FILES
success note 200 HTTP status code
failure note XXX in URL and 404 HTTP status code

Application Server
/export/home/accesmanagerinstalldir/opt/SUNWwbsvr/https-menfi.houston.rr.com/logs/access/server_access_log
192.168.1.199 - 08/May/2005:23:53:51 -0500 GET /pwc/PWCUnprotected HTTP/1.1 200 185
127.0.0.1 - 09/May/2005:00:02:34 -0500 GET /pwc/PWCUnprotectedXXX HTTP/1.1 404 1003
The log files illustrate the NameTrans wild card behavior
NameTrans fn="assign-name" from="/pwc(|/*)" name="passthrough"
All requests of the pwc context are passed on to the application server from the
web server as expected.
A nominal start of the server from the Web Server Manager yields the following output.
magnus.conf, obj.conf edit/configuration errors may be seen here.
