Scenario : I have an object (result set from DB) stored in memory cache (cache.Add(key, object)). This cache is having absolute expiration as cache policy. Some times I need to clear the object in cache (cache.Remove(key)) before the expiration. My application is running on IIS which should never be stopped.

Question: So my question is how can I achieve this using a separate application ? Or is there any other way to clear cache before it reaches the absolute expiration ?

You can't clear a browser's history via code because of browsers security reasons.

He means the cache on the server not the client I believe

I am not talking about browser's cache. I am talking about my application cache.

As you're using ASP.NET you probably need to create a button and/or page that will do this, and this will trigger the code on your ASP.NET server to call cache.Remove(key).

Assuming clearing the cache is something you don't want normal users to do, the best approach is to put the page/button somewhere they cannot access it, or hide from normal users.

If you're using webforms, perhaps create a button on your page that when clicked performs the cache.Remove call, and set visibility to true only if it's you logged in.

If using MVC, perhaps a link that calls a method on the controller which calls cache.Remove

Thanks for your reply Richards!

But I am invoking a WCF service which puts the objects in cache. So in such a scenario how can I achieve removing the items from cache ?

You didn't mention that. So create a WCF method that clears the cache and create a button/page/link that calls this method.
