 ===== Passed Data =====
+The passed [[xref>Doku_Event]] object has the fields: ''$data'' and ''$result''.
-$data is an array of header strings. There is one DokuWiki header ''%%'Content-Type: text/html; charset=utf-8'%%''. Handlers of this event can add/modify/delete the headers in the event data. The event data must remain an array, even if emptied.
+The ''$data'' field is an array of header strings. This array has default one entry:
+  * the DokuWiki header ''%%'Content-Type: text/html; charset=utf-8'%%''.
-===== Plugins handling this event =====
+The BEFORE handler of this event can add/modify/delete the headers in the ''$data'' field. The event data must remain an array, even if emptied. The default action [[xref>act_sendheaders()]] will output the headers, but this can be prevented by ''preventDefault()''.
-The following plugins are known to handle this event and their source code may be a good start for understanding and implementing a handler yourself.
+The ''$result'' field is always null, because the default action don't set this field. The AFTER event handlers comes (default) after outputting the headers.
