Limiting the viewable extent...

[Bob Basques]

All,

One method you might try, would be to use the new include mechanisms in 
the MAPFILES and have a separate MapFile header for each client.  You 
need to set the Extents somewhere anyway, just keep a separate header 
file and include the LAYER defs from a separate central file.

Although, this is not full proof with regard to locking folks out if 
they now the names of the MAPFILE headers for requesting.
