I wanted to give the QA team a way to clear the items in the cache during their testing so I justed added a button to the main QA test page with a button that runs the following code. I actually ripped this code from my book, Pro ASP.NET for SQL Server.

using System.Runtime.CompilerServices;
using System.Web;
using System.Web.Caching;

// ...

[MethodImpl(MethodImplOptions.Synchronized)]
public void ClearCache()
{
    Cache cache = HttpRuntime.Cache;
    List<string> keys = new List<string>();
    foreach (DictionaryEntry entry in cache)
    {
        keys.Add((string)entry.Key);
    }
    foreach (string key in keys)
    {
        cache.Remove(key);
    }
}
