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

[Karina Guardado]

Do you have an example please using  this part where you mention "the
layers property on the control (not documented
but see the source code) to specify a hidden layer by which the query is
done on". Also if you have a link to an example how to use the Post method
please.

Thank you so much for your help
