2003-07-01 Thread Alex Shneyderman 
Before you send any data in the response you can 
Send the following thru your response object:

% 
   response.setDateHeader (Expires, 0);
   response.setHeader (Pragma, no-cache);
   if (request.getProtocol().equals (HTTP/1.1)) {
  response.setHeader (Cache-Control, no-cache);
   }
%

Note, however that users can still go back in history
And resubmit their data. Browsers maintain history list
And unfortunately they do remember form data too. So if
Your user submitted a request and then clicks back button,
The browser will ask him/her if he/she wants to resubmit 
the data? I saw a note somewhere in Ted's (I think) book 
about how you can prevent this kind of submission on the 
server side but have not explored that further. Now I 
can't even remember where I saw it. 

The gist of it is that before you send the form to be 
submitted by the user you stamp it, and remember what is 
it you still expecting from the user inside the Session 
context. If user submits the form with the right stamp 
the request is processed, otherwise you can tell the user
to stop resubmitting the same request.

You can configure Struts to ad HTTP no-cache headers to every response :

in struts-config.xml :
controller nocache=true/

You can add some HTTP directives to your JSP (or tiles layouts) like this :

head
meta http-equiv=expires content=now
meta http-equiv=pragma content=no-cache
meta http-equiv=Cache-Control content=no-cache
/head

use struts-config_1_1.dtd to get infos and validate your struts-config.

Your snapshot looks good. How do you know your controller element is not at all 
getting called ?

Just to confirm,  I dont need to place the following

  META HTTP-EQUIV=Expires CONTENT=-1
  META HTTP-EQUIV=Pragma CONTENT=no-cache
  META HTTP-EQUIV=Cache-Control CONTENT=no-cache

In my pages? It is cool not to see these repeated lines
