Prevent Back button on the browser

Hello There,i just like to ask if you have any idea of preventing the Back button of the browser to navigate back to the previous page after a user log in.

Ex:After a user successfully logged in to my website and he/she hit the Back button of the browser.I want this to not redirected to the previous page instead redirected to the same page which is my Main page.Also after a user logged out to my website and again he/she hit the Back button of the browser.I also want this to not redirected to the previous page instead redirected to my login page.

hope you get my point..

Thank you very much in advance..BTW,im using C#

Hey,

The simple answer is, there is no sure fire way of preventing the user from clicking the back button. At the end of the day, it is their back button, and they can click it if they want to :)

The question really is why are you wanting to prevent this?

Is it just that you don't want the user to see the login page if they are already in? If so, there are a number of other ways of doing this.

sorry gary if it is a little bit confusing..your right,if a user has logged in and he/she hit back button then it stays on the current page.and also if a user has logged out and he/she hit the back button then he/she redirected to the login page..thats all.

How are you doing your user authentication? Are you using Forms Authentication, or are you using the built in ASP.Net Membership Provider?

Hey,

Have a look here:

Notice how you can provide a default url to the login page, when "protected" pages are attempted to be accessed? also, how you can make pages only availalble to certain users, i.e. authenticated, anonymous, etc.

Hi Gary,are u sure that this is not a dead link?..because i cant browse it here in the office..

Nope, it works fine for me.

I am looking at the page just now.

What about these:
