Whether or not there is a load balancer in front of the application that is doing the caching might be irrelevant. I can't imagine a web app without one . . .
I suppose what you want is to distribute the cached data so that if a user gets routed to another machine the data will be there. Needless to say, but this will only scale so far . . . . There are lots of ways to grow, such as extracting out a service than handles access to some bit of data and then try to distribute across the machines in that service. . . Depending on your size, you might find that the simplest solution is to use sticky load balancing, but to build your application such that it does not require sticky load balancing to work. That is, use the cache as a non-definitive store: Always be able to retrieve the data if it is not in the cache. If you have sticky load balancing then you can use the cache as an optimization but not a necessity. If your problem is just with trying to keep data consistent . . . then you should try the TCP lateral cache with UDP discovery enabled. Do not allow gets, only puts and removes. . . Take a look at the site docs for more information . ..
