Hashtable in Cahe seems to have items removed

[bloodsugarsuckerfish]

Hi all,

I have in the ASP.NET cache a Hashtable of items. What seems to be
happening,is that some of the actual entries in the hashtable are
being removed, perhaps under memory pressure, when what I would have
expected is that the actual hashtable be removed.

I cannot see an other reason that the items would be removed, other
than by the Cache itself.

Has anyone else experienced this, is t expeced behaviour, or am I
missing something?

Thanks

Rich
