I am developing a C# ASP.NET application. I am using AJAX with a timer to refresh the data every couple of seconds.
I am performing searches on queries. When working on my localhost, everything looks good.
When working on a load balancer that addresses 2 servers, there is a problem.
Sometimes, when searching a couple of queries, i see results from my previous search.
When looking at the traces of the load balancer servers i can see that 1 server holds the current query in the session but the other server holds the previous query.
The result is that the user of my application gets the wrong data.
What could be the reason for that?
