[OpenLayers-Users] Problem with IE and "WMS with POST Requests to Avoid Long URLs" example

[Andreas Hocevar]

Hi,

it looks like you have found a bug. Please create a ticket.

As a workaround in the meantime, if your server supports CQL filters
(e.g. GeoServer does), you can try to use OpenLayers.Format.CQL to
turn your filter into a way shorter string, and pass it to the server
as CGL_FILTER parameter with a GET request.

Andreas.
