Re: Load balancing between different versions of a web application

[Pranjal Thakur <pranjalt@xxxxxxxxx>]

Hello,
My problem is mentioned in the previous post (see below). I want to add that I cannot use sticky sessions as the cloud that hosts our sessions is fully clustered and so has the ability to send requests to a different server instance in case the current instance fails. 

let me know if there is a way to achieve this.

thanks.

This is more of a theoretical question. 

I want to know if it is possible to do this:

I have various versions of a web application, each running certain number of instances.
When a request comes in, it goes to a certain instance of some version. 
I want the load balancer to now route further requests from this user to only the instances of the version it was first routed to. 
I can maintain a cookie or some other way to save the version number of the instance. But I need the load balancer to now take that into consideration for further requests. 

Is this possible and Is there any plugin available for this?

Any help will be appreciated. thank you.
