Hi Ivan and George,<br>
<br>
I just tested the site and it seems that the request sent works. Also
the proxy works. But do you need proxy when using GetFeatureInfo?<br>
<br>
maybe this has something to do with IIS?<br>
<br>

<pre wrap="">Hi,
first check if the normal request is working, without proxy. What does
firebug say if its not working?
