In the end I cludged it using a bit of hacked together reflection:
<%@ Page language="c#" AutoEventWireup ="false" %>
<%@ Import Namespace="Syst em.Collections" %>
<%@ Import Namespace="Syst em.Reflection" %>
<%@ Import Namespace="Syst em.Text" %>
<%@ Import Namespace="Syst em.Web.Caching" %>
<script runat=server>
override protected void OnInit(EventArg s e)
{
this.Load += new System.EventHan dler(this.Page_ Load);
base.OnInit(e);
}
private const string row = "<tr><td>{0 }</td><td>{1}</td><td>{2}</td></tr>";
private void Page_Load(objec t sender, System.EventArg s e)
{
StringBuilder outHtml = new StringBuilder(5 12);
outHtml.Append( "<table cellpadding=0 cellspacing=0 border=1>");
outHtml.Append( "<tr><td>Ke y</td><td>Value</td><td>Type</td></tr>");
// Grap the CacheInternal cache object from Cache using reflection
Type cacheType = Cache.GetType() ;
FieldInfo fieldCacheInter nal = cacheType.GetFi eld("_cacheInte rnal",
BindingFlags.De claredOnly | BindingFlags.No nPublic | BindingFlags.In stance);
Object cacheInternal = fieldCacheInter nal.GetValue(Ca che);
Hashtable _entries = (Hashtable)
cacheInternal.G etType().GetFie ld("_entries", BindingFlags.De claredOnly |
BindingFlags.No nPublic | BindingFlags.In stance).GetValu e(cacheInternal );
outHtml.Append( "<tr><td colspan=3>Count :" + _entries.Count + "</td>");
foreach (DictionaryEntr y entry in _entries)
{
Type typeCacheEntry = entry.Value.Get Type();
FieldInfo fldKey = typeCacheEntry. BaseType.GetFie ld("_key",
BindingFlags.De claredOnly | BindingFlags.No nPublic | BindingFlags.In stance);
FieldInfo fldValue = typeCacheEntry. GetField("_valu e",
BindingFlags.De claredOnly | BindingFlags.No nPublic | BindingFlags.In stance);
outHtml.Append( string.Format(r ow,
fldKey.GetValue (entry.Value).T oString(),
fldValue.GetVal ue(entry.Value) .ToString(),
fldValue.GetVal ue(entry.Value) .GetType().ToSt ring()));
}
literalOut.Text = outHtml.ToStrin g();
}

Hi,
Does anyone know how to examine items in the ASP.NET cache that are added
using the OutputCache directive in framework 1.1
i.e.
<%@ OutputCache Duration="300" VaryByParam="No ne"
VaryByCustom="c mscontrol,cmsro le"%>
By examine I mean see their value, key and expiration time.
Cheers Ed.
