 For a long list of layers with long layer names it is possible that one
 hits a URL length limitation in IE6 to IE8 with the GET request. The
 problem is that the WMSGetFeatureInfo Request often fully repeats the
 layer list, once in the LAYERS parameter and once in the QUERY_LAYERS
 parameter. See http://support.microsoft.com/kb/208427 for the URL length
 limitation.

 To work around the problem I suggest to introduce a new requestMethod
 parameter in OpenLayers.Control.WMSGetFeatureInfo which allows to use a
 POST instead of a GET request. Of course the WMS server would have to
 support POST as well. I checked with mine (QGIS server) and it will
 support POST requests soon.
