Zohar, Not exactly clear on your requirements. Do you care which backend server the client is initially redirected to?
If not, then you can use a load balancer that supports "session affinity". It will use a load-balancing algorithm to initially decide which back-end server to forward a particular client to. Afterwards it will redirect all requests from the same client to the same backend server - until the session times out, which is configurable usually). You can of course use a dedicated load-balancing appliance to do this. Current versions of Tomcat also ship with a load-balancing application application that might work for you. However a lot of people use the Apache web server with its associated mod_jk module to perform this function. I have used it a year and it works fine for this. Here is the doc on the mod_jk connector: http://tomcat.apache.org/connectors-doc/index.html Here is the tomcat load balancer doc: http://tomcat.apache.org/tomcat-5.5-doc/balancer-howto.html You should also search the archives for this mailing list, there have been many posts in the past on this topic: http://marc.theaimsgroup.com/?l=tomcat-user&r=1&w=2 HTH - Richard -----Original Message----- From: Zohar Amir [mailto:[EMAIL PROTECTED] Sent: Sunday, January 08, 2006 6:03 AM To: Tomcat Users List Subject: distribution Hello, I've used tomcat to run some naive servlets, and now I need to do something more complicated. I need to be able to distribute my service. Clients connect to a tomcat server and their requests are forwarded to a backend server. I need to be able to distribute all this, so that clients can connect to any of a number of tomcat servers and then be "directed" to the same backend server throughout their session (until they log out). Can anyone point me to where I can read about such a solution? What I thought was maintaining a database with a mapping of session -> backend server, and use it, but this requires querying the database for each transaction... Any other ideas?] Thanks, Zohar. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
