[UMN_MAPSERVER-USERS] Limiting the viewable extent...

[Steve Hall]

Hi all,

Is it possible to restrict the users viewable extent of the map through 
the map file?  For example, I have data loaded for the whole of the 
country but I want it to be impossible for any client tool to view data 
beyond a defined and fixed extent.

The EXTENT parameters just seem to set the initial extent and you can 
easily zoom out beyond this extent.

I appreciate this is fairly easy to do through code but though that if 
this was possible via a mapfile then it would be done at the 'lowest' 
level...

Cheers,

Steve
