MWF GetFeatureInfo problem solved

[nelson guda]

It works! Thanks much!
That was definitely the issue.  Thanks also to Josh for spending a  
lot of time trying to help me figure this out.

Here is a summary of the problem for the record:

I was trying to get the WMS GetFeatureInfo request working on my  
mapserver copy.  I kept getting a response that looked like this:

> GetFeatureInfo results:
>
> Layer 'ira_fill2'
> Feature 689:


The solution was to put  'wms_include_items' 'all' in the METADATA  
block for the layer.

You can see the results here: http://roadlessland.org
It is a site that allows users to get info about inventoried roadless  
areas in US Forest Service lands.  The spatial data is a shapefile  
that is about 32mb.  The site uses Google maps and overlays the map  
with a wms layer from mapserver.  User clicks on the map are  
processed with a GetFeatureInfo request to mapserver.

Thanks for all your help, everyone.
