Clear Asp.Net cache from outside of application (not using source code)

asp.netcaching

I have a asp.net web application and I'm using cache (HttpRuntime.Cache) to save some stuff from db.

I also update db from time to time so that data in db does not match the data in my application's cache.

Is there any way how to clear my application's cache without modifying any source code or republishing the page?

I tried to restart IIS and to clear browsers cache but nothing helps.

Please help.

Create admin page for restarting your application and put

HttpRuntime.UnloadAppDomain();

to button_click or similar.

Here's a nice and simple cache helper class/service I use:

using System.Runtime.Caching;  

public class InMemoryCache: ICacheService
{
    public T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class
    {
        T item = MemoryCache.Default.Get(cacheKey) as T;
        if (item == null)
        {
            item = getItemCallback();
            MemoryCache.Default.Add(cacheKey, item, DateTime.Now.AddMinutes(10));
        }
        return item;
    }
}

interface ICacheService
{
    T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class;
}

Usage:

cacheProvider.GetOrSet("cache key", (delegate method if cache is empty));

Cache provider will check if there's anything by the name of "cache id" in the cache, and if there's not, it will call a delegate method to fetch data and store it in cache.

Example:

var products=cacheService.GetOrSet("catalog.products", ()=>productRepository.GetAll())

I think in the following post nicholas did explain the same scenario. Please go thgrough it asp.net 2.0 cache api will not work for web garden. You have do some third party caching mechanism.
