I'm starting to think that just handling this with a mapscript wrapper
script might be the easiest approach. Any thoughts?
Thanks,

thanks, nice idea. I tried it, and that did not work...

What about using GROUPs or layers with the same name where the second
layer
is TYPE QUERY?

I discussed this issue with Tom K. on the IRC yesterday, and he
thought it was of general interest and should be posted and
potentially requested as a feature.
Scenario: we have a Geologic map that has super complex cartography
that we don't want to reproduce in the mapfile (600+ classes, tons
of patterns, etc). So we dumped out a raster of it to serve as WMS.
However, when the user does a GetFeatureInfo on this WMS, we want to
return attribute data from the original shapefile.
I can envision this being taken care of at the layer level as a
metadata tag like "WMS_query_redirect".
In the short term we're working on a little apache mod_rewrite magic
to take care of it :-)

Percy
