Thanks for your reply.
Yes, But other also using same but problem with this page only.
Like this:
PROCEDURE outputHeader :
/*------------------------------------------------------------------------
Purpose: Output the MIME header, and any "cookie" information needed
by this procedure.
Parameters: <none>
Notes: In the event that this Web object is state-aware, this is
a good place to set the WebState and WebTimeout attributes.
------------------------------------------------------------------------*/
Output-http-header("Expires":U, "0":U).
Output-http-header("Cache-Control":U, "No-Cache":U).
Output-http-header("Pragma":U, "No-Cache":U).
Output-content-type ("text/html":U).
END PROCEDURE.
