Manually clear ASP.NET server cache for a single application/web site?

Question

How can I manually clear ASP.NET server cache (IIS 7) on a given application/website, like what can be done in IE to clear browser cache for a given domain?

Answer 1

Use the following to remove all objects from the cache

IDictionaryEnumerator enumerator = HttpContext.Current.Cache.GetEnumerator();

while (enumerator.MoveNext())
{

    HttpContext.Current.Cache.Remove((string)enumerator.Key);

}

Also, it is a bit of a sledgehammer option but you can restart the entire application as follows:

System.Web.HttpRuntime.UnloadAppDomain();
