It's Friday afternoon man! Even Mark isn't thinking about Struts over there
in Blighty, most likely nursing a warm beer. ;-)

A way of knowing where you came from, is to pass a parameter called "url"
that has the value of the page where you came from. But, I want to STRONGLY
DISCOURAGE you from doing such a thing. Treat your web app as a state
machine and if you know where you are and what your state is, then you'll
only ever have to worry about where you can go next and ignore piddly
details like where you have just come from. This WORKS VERY WELL, and I just
did it so I'm not talking from anywhere south of my neck!

I've heard someone mention before that they maintain a stack on the session
with all "GET" type requests.
That way, they can go back to any one of them and not worry about needing
submitted data.

Use tokens (see docs for more details or the struts-example for a running
example)

Subject: Forwarding Back to one Of Many Pages


I'm sure this has been asked before.  Several pages can link or forward to
my page.  My page is mapped to a DispatchAction (because I need to get some
initial data and then process the submitted data.)  After submitting, the
user is forwarded to another 'action succeeded' page.  I need to know how to
get the user back to whatever page they used to arrive at my initial page.
The user could cancel and I would have to get them back to the original
page, or the action succeeds and I have to get them back to the original
page from the 'action succeeded' page.  How can I do this?

Lastly, how can I prevent the user from bookmarking the form page or 'action
succeeded' page.  Or at least, how can I make the bookmark be a page I want
it to be (i.e., the initiating page in a chain of pages?)

Thanks.

Forwarding Back to one Of Many Pages

I'm sure this has been asked before.  Several pages can link or forward to
my page.  My page is mapped to a DispatchAction (because I need to get some
initial data and then process the submitted data.)  After submitting, the
user is forwarded to another 'action succeeded' page.  I need to know how to
get the user back to whatever page they used to arrive at my initial page.
The user could cancel and I would have to get them back to the original
page, or the action succeeds and I have to get them back to the original
page from the 'action succeeded' page.  How can I do this?

Lastly, how can I prevent the user from bookmarking the form page or 'action
succeeded' page.  Or at least, how can I make the bookmark be a page I want
it to be (i.e., the initiating page in a chain of pages?)

Thanks.
