I've got a weblogic cluster (8.1 SP3) set up and an Alteon load balancing t=
he connections on the front end. I followed nortel's weblogic doc to use pa=
ssive cookie persistence to maintain sessions to the same weblogic server t=
hat set the original JSESSIONID cookie, however it does not appear to be wo=
rking. I am wondering if anyone else has tried the passive cookie inspectio=
n feature of the Alteon 2424 or equivalent with the weblogic cookie and how=
you fared. The nortel doc is a bit out of date and I am hoping that it's a=
simple misconfiguration.

I am not sure if your problem has been fixed or not but I successfully conf=
igured load balancing with a Alteon 2424 using cookie insertion/passive coo=
kie inspection. I am running weblogic server 8.1 SP4 and I have got 4 manag=
ed servers in my cluster.

Have anyone tried to load balance their web servers and application servers=
using the same physical hardware load balancer (Alteon 2424)?=20
Note: I can provide more detail information or configuration setting if any=
one thinks they know how this can be achieved.
### My Web Tier ###
I am currently using cookie insertion (with the default AlteonP cookie) to =
load balance the web tier which consisted of three physical web servers and=
they are all running iPlanet. Proxy plug-ins is configured to point to a v=
irtual ip which consisted of four real application servers. See below
### My App Tier ###
The application tier consisted of four physical application servers and the=
y are all running weblogic 8.1 SP4. I am currently using passive cookie ins=
pection to load balance this layer.
### Problem that I am facing ###
Request to the web tier (via the web vip) is load balancing correctly.
Request directly to the app tier (via the app vip) is load balancing correc=
tly.
Request to the app tier (via the web vip) is "not" load balancing properly.=
For example, the load balancer is not inserting the AlteonP cookie all the=
time and it is only routing requests to one app server.
### What I think the problem might be ###
The reason why all requests are going to only one app server could have som=
ething to do with the connection pool between the proxy plug-ins and the ap=
plication servers. For example HTTP 1.0 vs HTTP 1.1 requests.
I currently have no idea why the AlteonP cookie is not been inserted all th=
e times.
It will be interesting to know how others weblogic guru configure load bala=
ncing for their web/application tier using Alteon load balancer.
