[OpenLayers-Users] How many layers can I use with "OpenLayers.Control.WMSGetFeatureInfo"

[Milo van der Linden]

Hello Karina,

That is a whole lot of layers. Since the WMSGetFeatureInfo uses the
http-get protocol, there are some (browser-specific) limitations:

Isn't it possible to combine layers? For instance, you now have a microred
layer per municipality, wouldn't it be smarter to make just one microred
layer and make sure that serverside they are all in one layer/file/table?
