[OpenLayers-Users] Cannot see Geoserver Vector Layer With WFS Protocol

Wed Oct 12 23:46:23 EDT 2011

Hi,

You are requesting data from a domain that is different from yours. 
You'll need to use a proxy script.
There is some more info about this requirement in the OpenLayers FAQ:
http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#ProxyHost

Regards, Roald
