bug in tomcat 5.5 and sticky sessions because of problem with jvmRoute
parameter?
hello,
i've just tried to set-up tomcat 5.5 with apache2 and mod_jk version
1.2.8 in a load balancing set-up with sticky sessions.
when i give as jvmRoute parameter the string tc1 my sessionids look like:
BF20EF21CC52EA0659B1E079015D7B56.tc1.tc1
and i see in the mod_jk.log file that no worker with the name "tc1.tc1"
could be found!
i've circumvented the problem currently by "doubling" the name in the
workers.properties file as follows:
-- snip start --
worker.list=load
worker.load.type=lb
worker.load.balance_workers=tc1.tc1,tc2.tc2
worker.load.sticky_session=True
worker.tc1.tc1.port=12013
worker.tc1.tc1.host=localhost
worker.tc1.tc1.type=ajp13
worker.tc2.tc2.port=12013
worker.tc2.tc2.host=remote
worker.tc2.tc2.type=ajp13
-- snip end --
was this problem already noticed? did i do something wrong? or should i
file a bug report?
thanks,
--

thanks for that hint, but actually luckily this is working.
the real problem is that the value that i specify for the jvmRoute is
"magically" doubled and i only doubled this name in the
workers.properties file as a short term workaround.
i still did not find out why this jvmRoute parameter is doubled in my
applications, but not in the servlets-examples/servlet/SessionExample
application.

Hi,
Take a look at:
http://jakarta.apache.org/tomcat/connectors-doc/config/workers.html
It clearly states that (big warning in red color)
The name of the worker can contain only the alphanumeric characters
[a-z][A-Z][0-9] and is case insensitive.
So tc1.tc1 is illegal name for the worker.
Mladen.

i've just tried this example myself and you're right. i see only ".tc1".
i have a very little webapp which does similar things to test the
distributed set-up and a our main big application and both have the same
problem with this double "tc1.tc1".
i will try to find out why i have it in the one case but not in the
other? nevertheless i anybody experienced similar problems and found out
where the problem comes from i would be very happy to hear about it.
thanks,
