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?

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();

I've never seen that method on httpruntime before

@Chris Mansic: It's there. I've used it before. Take a look here at MSDN: msdn.microsoft.com/en-us/library/…

Need to cast enumerator.Key to a string since Remove takes string and all keys are strings
I had the same problem, and recycling the application pool helped me. All my caches immediately reloaded as I wanted.
Ways of recycling the application pool are described here.
