Browser Back and Forward

Assume below scenario: You know if you
have logged on Yahoo! mail and when you are reading a
mail: 1 - if you press browser back button and come back
to login page 2- Then press browser Forward
button, you will be gone to Login page insetead of the
mail page.In other words, in client side you have
forwarded to other page. I want to have this
functionality in the login page of my application.but I don`t
know how? I have a loggin.jsp page I
appreciate your comments, Saeed

We haven`t ignored your question... I`m just
researching how to do this... The servlet API has access to a
history method... I`m just trying to see how to do this
and test it out. We`ve been using a
"breadcrumb" mediator in our development which is kept in
session and keeps track of where the person has been. You
get the URI and push it on a stack in the mediator...
But there should be another way to do
it. Stephen McConnell

I am not sure you will find the answer in the
Servlet API, Stephen. I believe that this will require
some client-side JavaScript work. I could be mistaken
though. I suggest to the author of the original post that
you do some research into JavaScript and see if you
can find an answer to your question there. One
other thought: will the forward button always pull the
next page from the cache? What if you force the page
to not be stored in the cache using HTTP headers,
thus forcing a request to be sent for the
page? Sincerely, Anthony Eden

I may not be understanding the question but I
can`t seem to reproduce the scenario. If I log in to
Yahoo mail and from the mail main page, click the back
button to the login page and then the forward button,
I`m at the mail home page again. FWIW I have
my browser set to refresh every visit to the page.
What am I missing? I know that JavaScript has the
history object that has back() and forward() methods so
maybe there`s something useful there.

Yeah... I was confusing some stuff I had seen in JavaScript. Mia Culpa,

You can try catch in JavaScript function which is
called by onUnload (<BODY
onUnload="unloaded()"> )"full login field and empty passw field" event and
forward to another page, if this is true. Good
Luck, Dmitry
