we use this feature in Fusion via mapscript to save the result of a
spatial or attribute query and then via the CGI (via OpenLayers by
merging new params queryfile=) to draw the query when rendering the
map. It is a *very* convenient and seemingly lightweight (at least in

I need queryfiles to persist query results (serialize to string/binary method
wanted!) as a part of whole map 'state'. But I need more convenient, handy
way to configure style of queried (selected) features. Style section to

The problem we have is that to efficiently process result sets from
database-based drivers we need to reference rows in the result set
rather than rows in the dataset. That means the results (with those
types of DATA/CONNECTIONs) can't be cached using the current
mechanism. Shapefiles would still
We may need to consider caching to a shapefile or something like that. You'd
be free then to reference that file as a layer. Slinging ids around is another
idea
I've used with OpenLayers. You pass the id into a selection layer by changing
an expression on-the-fly and in that case you'd have full
We use them with MapScript. Maybe it's possibile to activate saved
queries only with with a compiler option?
