<br>
I "solved" the problem by using 2 different proxy.cgi files ...
One is used for the WMSCapabilitesStore, and the other for
WMSGetFeatureInfo.<br>

<font face="Helvetica, Arial, sans-serif">Hello, <br>
<br>
I recently started using GeoExt2. With OpenLayers, I was using
this version of proxy.cgi : <a moz-do-not-send="true"
href="http://trac.osgeo.org/openlayers/browser/trunk/openlayers/examples/proxy.cgi">http://trac.osgeo.org/openlayers/browser/trunk/openlayers/examples/proxy.cgi</a>.<br>
<br>
With GeoExt2, I encountered problems to run a WMS
GetCapabilities. I solved it by modifying the proxy.cgi like in
this post : <a moz-do-not-send="true"
href="http://www.geoext.org/pipermail/users/2011-May/002287.html">http://www.geoext.org/pipermail/users/2011-May/002287.html</a>.<br>
<br>
But with this new version of proxy.cgi, the WMSGetFeatureInfo
query fails with the error 500 '</font>Some unexpected error
occurred. Error text was: list index out of range'. <br>
Actually the queried URL is URL encoded :<br>
