When you want that your requests that use specific parameters of the GIServer be compatible with OpenGIS WMS specification you should create styles. These sytles will make GIServer automatically add this non-compliant parameters needed to your applications. A style can be declared at the Server level or at the dataset level .

An example of such a request is

  REQUEST=GETMAP&
  LAYERS=TERRA.PATHFINDER,TERRA.BORDERS&
  BBOX=-10,32,20,47&
  WIDTH=200&
  HEIGHT=100&
  FORMAT=GIF&
  TERRA.BORDERS.PEN=2

Where the GIServer paramenter PEN is used for the TERRA.BORDERS layer.

Using Styles the request respects the WMS specification and will be defined as :

  REQUEST=GETMAP&
  LAYERS=TERRA.PATHFINDER,TERRA.BORDERS&
  BBOX=-10,32,20,47&
  WIDTH=200&
  HEIGHT=100&
  FORMAT=GIF&
  STYLES=,STRONG
