cache enumeration from web page

I'm caching aspx pages and ascx controls as well as programmatically within
aspx code for my asp.net web application. I'd like to have a special admin
aspx page that will display the contents of the cache. I'm using the
IDictionaryEnumerator, see code snippet below, but this just gets me the
value or data type and the key of the items entered programmatically.

Here's the question. I'd like more information, such as when it was added
and when it will expire, also, what pages and controls are in the cache and
when they will expire. How do I do this?

...........
If nCacheCount > 0 Then
Dim CacheEnum As IDictionaryEnumerator = Cache.GetEnumerator()
While CacheEnum.MoveNext()
drCache = dtCache.NewRow()
drCache("name") = CacheEnum.Key
drCache("value") = CacheEnum.Current.Value.ToString()
drCache("na") = ""
dtCache.Rows.Add(drCache)
End While

thanks, -phil

that info isn't exposed to the outside world because of the dictionary
implementation. what you see is exactly what you get.

Thanks Alvin. Ok then, how about a tool of some sort for the IIS
Administrator that would expose this cache information locally to the
console? Secondly, what is the appropriate counter to moitor through the
performance counter that would reveal cache usage?

Well, if a tool can do it then user code can do it. That isn't the case. In
any case, a tool runs outside of the executing process which definitely does
not have access to the cache instance. I'm not aware of any counter that
monitors cache usage, counters can measure memory usage which is directly
dependent on cache usage. What exactly are you after? Are you having memory
issues?

I had issues early on with properly saving data in the cache the way I
wanted. I desired a tool to inspect the cache to help analyze what was
happening. Having solved the issues I was left with the curiosity of how to
inspect the cache. Thanks for your time and setting me straight. -phil

In ASP.NET performance monitor countors, there are some like "Cache API hit
Rate" and "Cache Total entries". But they cannot go to the detals like when
a cached object was added and expired.
