[ka-Map-users] dynamic layer

[Luca De Felice]

Thank you Luca for your flash answer.
So you are telling me that using the tile_source,redraw_interval and 
refresh_interval metadata for
 the polygonal layer I will fix my problem, but I need to modify the 
attribute 'risk' in my shapefile (for instance modifing the dbf file) every 
20 minutes, Do this cause problem to my webgis application? because the 
mapfile refers to this shapefile.

thanks again
Luca
