Question

We have a website that runs on two load balanced servers. We used the ASP.Net Application variable to make application state “online/ offline”, or for some important messages across the application,
So when i try update a application variable its available on one server but not on other.
How i can manage a application variable across load balanced servers.
What may I use? Of course keeping it as simple as possible.

Answer 1

Are you using sticky sessions? How often does the data change? Is application cache even necessary?

One option: You can have each webserver store (and manage, refresh, invalidate) its own application cache. But then you run the chance of storing different copies.

Another option: distributed cache such as memcached or ncache or something else.

Another option: read/write the data out to a shared disk.
