there is the diff with rc4.

i switched all the WHERE clause for a INNER JOIN ON INTERSECT.
i do the transformation on the POLYGON and not the geometry of the table.
the request does one transformation on the polygon and not many
transformation as the WHERE clause.

and i thought about my srid problem, and maybe i don't need the table's
srid.
if the layer's srid is always the same of the table's srid.
ows_srs_get_srid_from_layer() return the srid of the tag "wfs_srs" in my
mapfile ?
