Hi Barend,

I got my mapfile corrected and my map is displaying fine.

My mapfile is like this:

# (Created with PyQgis MapServer Export plugin)

Problem is Openlayers.loadUrl(url, '', this, setHTML) does not work.
 It is saying Jscript runtime does not support this Object or property.

My script for calling GetFeatureInfo is as below:

        function setHTML(response) {

response.responseText;
        }
   
   
   
   
    </script>
    </div>
    <div id="nodelist">
   
    </div>
    </form>
</body>
</html>

I think it has something to do with proxy.I am showing map on a aspx page
using IIS.Could you pls try it yourself and let me know if it works for you.

thanks.
