[mapserver-dev] draw query output over the map

Check out the QUERYMAP object... (http://mapserver.org/mapfile/querymap.html) Via URL you'd do something like this assuming you've set a QUERYMAP up:

  http://.../cgi-bin/mapserv?...query params...&qformat=png24

This would render the query results to an image. You can also combine a query map and template output.

Subject: [mapserver-dev] draw query output over the map

Hello all
I am using mapserver with postGIS. everything is working fine.
my requirement is: I want to highlight the query output features through postGIS over the map i.e rendering the query features.
for example the the intersecting features will take red color after the query is submitted.
in ArcGIS server there is a graphic layer concept, which allows to add graphic layer to the map at client end. Similarly there is a note concept in ArcGIS Explorer.
How this can be achieved in mapserver? after the query a new layer is being generated , how that can be drawn over the map?
please help
thanks in advance
