I need to load-balance trafic with a persistence based on http header "X-Nokia-MSISDN".

Knowing that I'm using the version 4.1(6), the command "http header sticky" is not available (version 4.2 and more).

I've seen that the following command is available "persistent rebalance" with version 4.1(6) but I'm not sure about what is its action.

According to the definition given in the guide (

"The CSM allows HTTP connections to be switched based on (...) fields contained in the HTTP header."


How can you define that persistence should occurs on the "X-Nokia-MSISDN"

http header ?

Thanks for your help

the persistent rebalance command tells the CSM to look at every HTTP request to select the best server. So, if you have a persistent connection ( 1 tcp connection for many http requests ), the CSM will look at each request.

Otherwise, it only looks at the first request and assumes all the other requests stick to the same server. Which is normally true, except if you have a proxy connecting to your vserver.

You still need 4.2.x to allow sticky on header info.
