[OpenLayers-Users] openlayers,geoserver in external web app

[pierre de fermat]

Thanks Tue. I managed to redirect it and it works. However, this approach
cannot handle exceptions. When i fake the wms call, and if the struts layer
encounters an exception (session related, db timeout etc) , I just end up
with an empty image. I am not able to redirect such a request via
struts.xml or any other means. The proxy method would also face similar
issues.

Any thoughts?

Best
Pierre
