Avoid Back Button Click

[IamAmit]

Hello friends, I wanted to put restrictions on users browser activities. When user logs in ...if he presses "Back" button of the browser...he must not go back to the login page..an error message should be displayed to the user..How can we check that? Thanks In advance

Why do people ask this day after day ? How does anyone think it's remotely possible ?

Becaus every secure system (eg, banking websites) log you out if you try to click back. Obviously this is a much more indepth system than just "avoid user clicking back button", and requires much more work than a simple javascript hack.

Yeah, these folks all ask the wrong question, that's the core problem

Offcourse ..It is a bit of difficult code...than just javascript code ...but We need that code..Can anyone help us?

[eyeseetee]

try putting this in your code javascript:window.history.forward(1);

[Christian Graus]

That is close to useless.

*sigh* It's really very trivial. You CANNOT stop the back button. You CAN make every page check if a session variable is set, and if not, redirect to your login page. I use a base class for this.

Hi, Instead of doing a redirect to next page do a javascript location.href='next_page'
