<br>
Have you seen: <a
href="http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#ProxyHost">http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#ProxyHost</a>
?<br>
<br>
It's been a while since I had need to set up a ProxyHost but I think that
OpenLayers appends the complete URL that it is looking to request data from to
the URL specified as the ProxyHost.<br>
<br>
Hope that helps,<br>
<br>
Matt.<br>
