How user will reach log in page

siri_suresh

Hi All
I have a problem, whenever the user sign out from his session and presses browser back button then he should be taken up to sign in page not previous page. You can see this functionality in www.mail.yahoo.com site. How can i do same thing using PHP and JavaScript. Example code will do more help for me. Please help me in regard
Thank you
Suresh

In fact the user will go to the beck page,
but after is redirected to login page.

The idea is: in every page that require a user login to check if is a valid session or no.
If the session is not OK you have to make a redirect with header('Location: /login.php')

in login page, after submit you have to o something like:
-check user/passwd
- if user/passwd OK setCookie($a_cookie);
in $a_cookie var you shuold keep some info about user

after that... in every page that require for user to be logged you have to do something similar with:
if (!isSet($a_cookie))
header('Location: page_login.php');
