[Users] GetFeatureInfo selecting with a polygon instead of a point

[Lluís Peinado]

Hi, selecting within a polygon (as far as I know) isn't supported by WMS.
Think about using WFS responses instead and their geometries, if you don't
want to deal with it, maybe putting your data on a postGIS database and make
a column in the bigger polygons layer with some reference to the lesser
polygons that they intersect or contain.
Also mapscript (if you use Mapserver) can help you.
