Right then. Except, I want *all* my classes to be drawn if no class has been
provided. And, if one or more classes have been provided, then I want only
those to be drawn. So,
http://server/mapfile?mode=map
should return a map with all the 100+ classes in a layer. And
http://server/mapfile?mode=map&classes=Foo,Bar
(or some other variation of the above) should return a map with only the
requested classes in the layer. I can't think of anyway of doing the above
without resorting to scripting, and I still have had no luck with WMS returned
from Perl MapScripting.
Suggestions.
