LB problems - 'too many directs'.

So I am trying to put our ezproxy behind a Load balancer. We have two nodes, and have the following config for each:

LoginPort -virtual 80
LoginPortSSL -virtual 443
LoginPort 8080
LoginPortSSL -http 8081

The LB is offloading https->http to port 8081.  Non http traffic is going to port 8080.  I can get each separate exproxy node to work just fine, but as soon as I have both running at the same time, all hell breaks loose.  I am getting 'to many redirects, as soon as I try to access resources.  I am guessing that this is because Ezproxy must make redirects to itself, and has no way of knowing which session it came from, and so is bouncing around.  I actually tried this config:

LBPeer -host=ezprtstap21.int.its.rmit.edu.au -http=8080 tstezpalum1
LBPeer -host=ezprtstap21.int.its.rmit.edu.au -https=8081 tstezpalum2

LBPeer -host=ezprtstap22.int.its.rmit.edu.au -http=8080 tstezpalum3
LBPeer -host=ezprtstap22.int.its.rmit.edu.au -http=8081 tstezpalum4

But it doesn't appear to do anything.

Has anyone gotten their Ezproxy environment working behind a LB with multiple nodes?
