Daniel,
Thanks. What do you think of adding it to the 5.0 plans to add
MAXEXTENTS tag to the MAP object that would do this? This question seems
to come up fairly regularly in one context of another.

In MapScript, the mapObj methods zoomPoint() and zoomRectangle() take a
maximum extent for that purpose, but I don't think there is any way to
set a limit on extents in the mapfile directly that would apply to the
mapserv CGI and WMS interfaces.

Steve,
I may be confusing this with a feature of ka-map, but I'm not sure.
Steve L do you know if there is such a feature in mapserver?

ps: lots of Steve is confusing!

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...
Yes, I believe you can do it by setting METADATA values for the MAP
object. I just check the mapfile reference and it is not described
there. Could you please write a documentation bug to request all
METADATA controls be documented.

Thanks for this Steve, do you happen to know off hand any of the
relevant keywords to this problem (to get me started). I could take
a look through the code and dig deeper if I have somewhere to
start. This will also enable me to file a more accurate and useful
bug...
Cheers,
Steve H
