WFS request options

[nelson guda]

Thanks Josh,

I looked over the WMS GetFeatureInfo request, and this is exactly  
what I need.  For some reason, though the only data I am getting back  
looks like this:

GetFeatureInfo results:

Layer 'ira_fill2'
   Feature 689:


The feature number appears to correspond to the correct place in the  
dbf file, but none of the rest of the feature data is being  
returned.   I don't understand.  Does anyone have any ideas?

thanks,
nelson


Here is the mapfile and request that I made:
