[OSGeo-UK] How do you use OpenLayers.ProxyHost?

[Matt Walker]

Hi Peter,

Have you seen:
http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#ProxyHost ?

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.

Hope that helps,

Matt.
