URGENT - Session stickyness lost with cookies disabled
Hi,
Is anyone successful with mod_jserv load balancing with stickyness when
cookies disabled?
I am running Tomcat 3.2.1 and apache 1.3.12 with mod_jserv on sun solaris 2.6
I have configured apache for load balancing between 2 unix servers and it
is working fine when cookies are enabled. The requests are load balanced
between
the 2 servers and session stickyness works fine (once the session is
established
the request is always routed to the right app server based on the suffix in
the jsessionid).
But when the cookies are disabled (I am encoding encoding the url) the
requests are
distributed between server1 and server2 meaning doesn't stick to the same
app server.
When there is a request from the browser (and the URL has the
jsessionid.suffix) the
mod_jserv doesn't route it to the right app server based on the suffix in
the jsessionid
and the session is lost (a new session id is created).
Here is the configuration I have in httpd.conf
<IfModule mod_jserv.c>
ApJServManual on
ApJServDefaultProtocol ajpv12
ApJServSecretKey DISABLED
ApJServMountCopy off
ApJServLogLevel notice
ApJServShmFile /apache/conf/jserv_shm
ApJServLogFile /apache/logs/jserv_log.log
ApJServBalance loadbalancer CCSF1
ApJServBalance loadbalancer CCSF2
ApJServHost CCSF1 ajpv12://server1:port1
ApJServHost CCSF2 ajpv12://server2:port2
ApJServRoute CCSF1 CCSF1
ApJServRoute CCSF2 CCSF2
ApJServMount /myapp/servlet balance://loadbalancer/myapp
</IfModule>
Any help is highly appreciated

Ah... Right. Duh. mod_rewrite would have nothing to do with
keeping track of state.

Right...I am using the encode URL and the jsession.suffix is seen in the
url everytime.
but by clicking or pointing at any of the links in the page shows new
jsessionid.suffix

Read the shell scripts. In this case, particularly, read the
'tomcat.sh' script; $TOMCAT_HOME/lib is right, so assuming on your
machine $TOMCAT_HOME is /var/tomcat you've put it in the right place.
Be aware, of course, that if you *don'T* start tomcat with the standard
scripts, your on your own.

tomcat hangs on stop
Posted by "Andrew B. Luck" <ab...@yahoo.com>.
hello,
i'm a newbie with a linux machine already configured with tomcat.
tomcat starts when the computer boots. i try to stop it using a script
(/usr/bin/tomcat) with the command 'tomcat stop'. it hangs with the message
'Stoping tomcat 8007 null'.
also, i am trying to get tomcat to a jar for jdbc. i've been placing it in
different folders (/var/tomcat/lib) for it to find. i've had no luck. how
can i determine which folder tomcat is looking to for jar files?
please help,
-andy

They are exclusive. Basically, for every link back into the web application
that needs to maintain session, the programmer must call and EncodeURL
function so that tomcat can add the JSESSIONID parameter to the URL at
execution time.
Apache URL rewriting allows the server to 'adjust' the incoming URL so that
it goes somewhere else.

What about the rewrite mod in Apache? Are the two
exclusive or do they work together?

Tomcat does support url rewriting, but the developer must have written the
web app to support it - otherwise no dice.

there are only two ways of tracking sessions
1. cookies
2. url rewriting
I don't know that tomcat supports (2)

Wouldn't you necessarily have to have cookies
enabled to get this to work since http is a
stateless protocol? I mean, what your asking
the protocol to do is something it can't do
without cookies, or something that it can use
to record session information.
