Hi to all,
I' ve to work with two application (Front End and Back End); this two have recall each other:
aaa.domain.it (on 1 cluster) have to make call to bbb.domain.it (on other cluster) and vice versa.
My Environment is:
WAS 6.1 Network Deployment with:
1 Load Balancer that manage http stream
2 HTTP server IHS
2 WAS 6.1.0.23 with 2 clusters (one for application).
What I've to do to make possible interaction between the applications? That one make calls by http stream so if it pass through the balancer it's not able to manage the stream because from the balancer the internal IP (the ones of the clusters) are not visible.
Thanks
Emanuele
Internally it would probably be ok for the two servers to know each other's real IP addresses (or internally managed hostnames), i.e. to access each other without going through the load balancer.

Hi Chris,
Thanks for your suggestion but my problem is that the calls by the single applications are made via HTTP Stream, so I've to pass through the balancer. What I want to know is if exist some setting that made possible the HTTP stream manage internally in WAS.
Thanks in advance
Emanuele
Well, not exactly...
Suppose your load balancer virtual ip address is n.n.n.1 and your two real servers have ip addresses n.n.n.2 and n.n.n.3
Normally n.n.n.2 and n.n.n.3 would be masked from end-users, or better still be on a non-routable back-end network, and all user traffic would be directed to n.n.n.1
But internally n.n.n.2 could explicitly access n.n.n.3 and n.n.n.3 could explicitly access n.n.n.2

I know it Chris but, in my environment both application have a dedicated cluster so, if I make a call to the single machine lost the benefit of the environement. I need to find a way to call one cluster from the other without pass through the balancer.

What's stopping calling their ports directly? I must be missing something...

Any Idea?
