With a centralized file area this will still work...

That's exactly why cached queries exist. Id's are written out to a
and then reused in lieu of doing
a new query. Have you looked into those? I've used them in a couple of
circumstances and they 
work quite nicely.

Hi There,

 I was looking into how to keep selected elements between page
What I want is to be able to show the selections (using draw query)
after a page has submitted without doing each time a query.  In some
applications, peopole want to do a query and do some panning, zooming
without their query being lost.

 I was thinking of adding a couple of utility functions to add shpes
id's to a resultcached used during the query. It will be less costly
time to use these functions instead of redoing the query every time.

Do You think It is a useful ? Any comments/objections ?
