public class WOExtraHeaderTag

extends TagSupport

This is a sub-tag of both WOComponentTag WODirectActionTag used to pass HTTP headers. WebObjects supports the use of WOComponents and DirectActions in JSP through the use of a Tag Library. While WOComponentTag and WODirectActionTag specify the WOComponent or DirectAction that is used in a JSP, this specifies an additional key-value pair to be passed as an HTTP header. This tag has no body but has the following attributes:

• key. The key of the header. Required.
• value. The value of the header. Optional. If this is not passed in, the header key will be removed from the HTTP request passed to the component.
