user restrictions / tiles

[Matthias Schulz]

1.
Is there a way to define the data of a shapefile shown on the map by
using an attribute query? I want the user to log in and show only the
information he is allowed to see, i.e. setting a query definition to the
shapefile(s) with mapscript. Does anyone have an example for this?
2.
For large datasets I assume it is faster to work with tiles, is that
correct? Can I combine working with defining the shown data by a query
as in point 1 and working with tiles?

Thanks a lot,

Matthias
