Class ResponseHeaderInfo

java.lang.Object
  org.zkoss.zk.ui.metainfo.ResponseHeaderInfo

public class ResponseHeaderInfo
extends java.lang.Object

Represents a setting of a response header. The setting specified here will become the response's header.

It is a bit confusing that ResponseHeaderInfo represents a setting of the response's header. HeaderInfo represents a tag located in the header of the generated content of a page. For example, if the client is a HTTP browser, then ResponseHeaderInfo is equivalent to invoke Execution.setResponseHeader(java.lang.String, java.lang.String) and Execution.addResponseHeader(java.lang.String, java.lang.String). And, HeaderInfo represents the <link>, <meta> and <script> HTML tags

It is not serializable.
