Syntax

Example

This example demonstrates how this works in a BBJSP web-page

<html>     <body>         <h1>Hello from BBJSP</h1>         <%             if !#Response!.containsHeader("MyHeader")               #Response!.addHeader("MyHeader","Something")             endif         %>     </body> </html>

This example demonstrates how this works in a BBJSP servlet

class public MyServlet   field private BBjspWebRequest request!   field private BBjspWebResponse response!   field private BBjspWebSession session!      method public void service(BBjspServletContext context!)             #request! = context!.getRequest()     #response! = context!.getResponse()     #response!.setContentType("text/html")     s! = #response!.getOutputStream()          s!.write("<html><body><h1>Hello from BBJSP</h1>")     if !#response!.containsHeader("MyHeader")       #response!.addHeader("MyHeader","Something")     endif     s!.write("</body></html>")   methodend classend
