<EXTRA-PARAMETER>

IMF Developer's Guide » Map Configuration » <EXTRA-PARAMETER>

The <EXTRA-PARAMETER> element is used in the <GET-MAP> and <GET-FEATURE-INFO> elements to specify extra (non-standard) parameters to add to the HTTP request. For example, if your WMS requires something like SPECIES=12345, you could set this like:

<EXTRA-PARAMETER name="SPECIES" value="12345"/>

The advantage of setting this extra parameter here rather than in the base href of the request is that the extra parameter value can be more easily changed from within IMF code using the setExtraMapRequestParameter(String, String) and setExtraFeatureInfoRequestParameter(String, String) methods.
