I'm trying to understand how wicket deals with
problems related to the browser back button. I know
that there's a parameter named "path" which is
incremented on every request and it is compared to an
attribute in session.
My questions are:
1. If we use the back button, the parameter value
becomes lower than the session value then the page is
marked as expired. Is this the main rule? If not, what
is it?
2. How is the session attribute incremented on every
request?
3. How is the parameter value set? I mean, I don't put
any hidden field in my forms with the name "path"
neither I write the parameter on my URL, so how it
went there on the URL?
If possible, I want more technical answers, not just a
brief explanation. I'm trying to learn to show wicket
in a java web development course in the future. I
appreciate any help. :)
David.
