[OpenLayers-Users] WMC and multi-url in OpenLayers 2.7

[Kralidis,Tom [Ontario]]

Correct, WMC 1.1.0 allows one Server element with one OnlineResource element.

I'm not sure whether OL supports OWS Context, but there you can define multiple Servers, and / or multiple OnlineResource URLs within a Server element, to handle something like this.
