[mapserver-users] Mapserver 6.0 regex

Hi Chris,

The cluster->filter can only accept mapserver expressions, filteritem and
regex at layer level does not affect this setting.

However I consider the layer level filter should probably work, could you
file a ticket by adding some test data and a mapfile example?

Best regards,

Tamas
