Dynamic back button

Hi,

I have a page that can be reached from various other pages. On this page is a button that will send them back to the page they came from via the action for that page. Is there a clever way of doing this with struts 2 other than putting a hidden variable in the page to check.

Thanks

Dave.

There are a couple of tricks
1. The referring page can be found in request.getHeader("referer")... 
the referring page's request parameters can not be found though so this 
will probably not work.

2. You can implement a javax.servlet.Filter
This pushes and pops pages (and their parameters) to a stack.
Pop occurs when back is clicked
When the user chooses an option from the main menu, you clear the stack
Back button (tag??) uses stack.peek(1) to get the prev page and it's 
parameters.

Send the url to get back as a parameter.
So you can just use EL in your link or javascript.

Regards,

Felipe
