[OpenLayers-Users] Array of url's not working with WFS protocol

[Bart van den Eijnden]

Hi Kris,

that actually slipped my mind when I said patches welcome :-)

The only way I see is to use an iframe hack instead of real XHR. The reason I also have been wanting to look into this is some security issues in IE with ActiveX, not all of my customers had ActiveX enabled, or somehow the XMLHttp one was treated as an untrusted ActiveX.

Best regards,
Bart
