Caching

[John S]

I have a page were data can be filtered using up to 4 listboxes. Once
someone does a filter, those parameters are saved so when they come back
to the page on a subsequent visit, the listboxes are filled for them.

There is a slight performance issue if all listboxes are set to 'All'.
Can the Cache Object be used for data that is static but filtered? If
so, how? The data that is being filtered is updated once a month and I
am not using the .NET platform.

Thanks
