can’t know that info_format=text/plain can’t work with the cascaded layer. Actually no info_format will work in this theoretical case because Geoserve is always using “application/vnd.ogc.gml” when it cascades GetFeatureInfo but our Mapserver was not configured
to support that.<o:p></o:p></span></p>

believe that it is even possible to do it generally in a reliable way so that any WMS could do it successfully with any other WMS. Probably Mapserver can do is in some cases because

<tt>I am building a cascaded WMS. My layers all have connectiontype WMS and all of them use one layer of the same WMS as source. The only thing I change is the style of the original WMS.
</tt><br>
<tt>My problem is that the GetFeatureInfo does not cascade. I am using Mapserver 7.0. I read that the GetFeatureInfo request supports cascading. All requests are enabled in the metadata. Do I have to add a special tag in the metatada or layer section to "pass
through" the GetFeatureInfo from the original WMS?</tt><br>
