Hi All,

Looking for a little guidance on load-balancing as it pertains IBM Http serv
er and Websphere Application Server.

Currently I have 3 machines with IHS and WAS loaded on each, serving the same application (Application_1) via
 IHS.  So, to access Application_1, I have my choice of going to http://machine1:9001, http:/
/machine2:9001, http://machine3:9001.

What I would like to do is pull the IHS server off of the 3 separate machine
s and have a single IBM Http Server.  I think this is possible, by configuri
ng the PLUGIN-XML.CFG to use a round-robin type scenario with each machine d
efined.  However, I don't k
now how to configure the httpd.conf file in this scenario, specifically the 
virtual host aliases.

Is what I'm trying to do even feasible?  Ultimately, all I'm looking at doin
g is having a single HTTP serve the same application from multiple WAS machi
nes. Any tips or guidance to other resources/reading would be most helpful!

TIA - mocatdaze@hotmail.com

This is not so.
All you have to do is change your plugin-cfg.xml so that the "UriGroup" elem
ent has an "Uri" element like:
<Uri Name="/appContextRoot/*.jsp"/>
In this case all the request for a ".jsp" in your application will be routed
 to the Application Server.
All the rest (.jpg, .html, .js, etc...) will be ignored by the plugin an mus
t be served by the HTTP server.
Of course you have to make sure the IHS can find those other files.
Hope this helps.

Regards,
RHL
