Hi Konstantin,
Our Balancer is setup as follows:
<Proxy balancer://dsmdelivery>
BalancerMember http://lsa-cmsproddlv1.lsa.umich.edu:8080 retry=2
BalancerMember http://lsa-cmsproddlv2.lsa.umich.edu:8080 retry=2 status=+H
ProxySet stickysession=JSESSIONID|jsessionid
</Proxy>
Yes, it worked as-is before.
The funny thing is that both server names on the same VirtualHost are
serviced identically by the same Tomcat engines, yet with a different
outgoing 302. I also notice that the correct (single-slash) 302 has
"Transfer-Encoding: Chunked", while the "//" 302 has a
"Content-Length:0" header as one of the main differences. The F5
load-balancer Cookie may be ignored in the "www.lsa.umich.edu" case.
I appreciate your questions and thoughts.
Thanks!

All,
We are running into a peculiar issue. We have Tomcat 6.0.24 front-ended by
Apache2.2.3. We have a VirtuslHost serving port 80 where Apache simply
hands off "/" to Tomcat's load-balancer.
<VirtualHost *:80>
ServerName wwwprod.lsa.umich.edu
ServerAlias wwwprod www www.lsa.umich.edu
Redirect / balancer://dsmdelivery/
ProxyPass / balancer://dsmdelivery/
ProxyPassReverse / balancer://dsmdelivery/
TraceEnable Off
</VirtualHost>
The examples in [1] do not have trailing "/" neither in <Proxy>
element nor in ProxyPass setting, while [2] has one such example
(search for "A sample balancer setup").
[1] http://httpd.apache.org/docs/2.1/mod/mod_proxy_balancer.html
[2] http://httpd.apache.org/docs/2.1/mod/mod_proxy.html#proxypass
So, how is your <Proxy> element configured?
The problem cropped up when all systems including the F5 load-balancer
had to be rebooted after last weekend's storm.
So it did work before?
Best regards,
Konstantin Kolinko
