i try to implement a logout feature like yahoo, squirrelmail, etc.
That means, when you klick "logout", you are redirected to a logout page.
When pressing the browsers back button, you are redirected to the login
page again.
This could look something like that (independent of caching - so you
don't need to set headers):
Layout.java (or a BasePage.java):
Object onActionFromLogout()
{
loginService.logout();
return Logout.class;
}
public Object onActivate()
{
if(loginService.isAuthenticated())
return this;
else
return Login.class;
}
I've tried to implement that with:
@Inject
private Response response;
...
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma","no-cache");
Where do you add this two lines? This should work if you add the headers
before content is sent. I just tried that with the quickstart archetype
- I added the following lines to the Layout.java and it works:
@Inject
private Response response;
@BeginRender
public void addHeaders()
{
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma","no-cache");
}
