Jody,
Thanks for your reply.
And great suggestion to use the native projection for the accurate reason.
thanks,
Lingbo

Interesting. I would normally expect the GeoTools datastore to handle this -
but you are correct if you can tell up front that there is no data in the
provided bounds you could avoid instantiating a datastore completely.
A couple of notes of caution. Lat long bounding box is fairly lax, you may find
it more accurate to project the request into the native projection and check
against the native bounds.

Hi Geoserver community,
For every WMS layer that has latLongBoundingBox set up in the config, GeoServer
may restrict the request to the configured latLongBoundingBox. At the moment,
it doesn't, and this results in unnecessary query and wastes connections and
cursors (for Oracle).
Thus I propose to add an option in the code for latLongBoundingBox range
checking. the option will allow to filter the none result query which is out of
latLongBoundingBox range and improve the performance.
If community reckon that it is the right way, I am willing to submit a code
patch to implement it if necessary.
Thanks first,
Lingbo
