keep in mind that folks like us (GlobeXplorer) generally have a bank of machines front-ending traffic, being fed by a load balancer (such as: http://www.f5.com/f5products/bigip/)

therefore, don't assume that one click to the next hits the same machine...one would want to use an extensible session object something extensible that might have a default implementation in a RAM, but can definitely use a centralized db or nfs area...

Subject:	[Mapserver-dev] Add shape id's in the selection
Hi There,

 I was looking into how to keep selected elements between page submits.
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 in
time to use these functions instead of redoing the query every time.

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