Some times you may want to remove all items from cached memory and fill it by
new data.
Session State has a method for emptying Session memory for specified user (Session.Abandon()
).
but in Cache object there is no the same method. with simple technique you
can do it.
IDictionaryEnumerator enumerator = HttpContext.Current.Cache.GetEnumerator();
while (enumerator.MoveNext())
{
HttpContext.Current.Cache.Remove(enumerator.Key);
}
Note that, this technique is not efficient for pages with
OutputCache type. for clearing this type cached memory, you should use below
code line.
Have a good time.
