how to disable the back button on the browser using jscript?

[gd69]

i've noticed that many websites compromise on security.one such security issue is that once a user log's out of his account,he can still view the previous page by clicking on the back button of the browser as the page will load from the cache.....not the server. the user mat not be able to click on any links,etc. but he can atleast view the page.i have disabled the caching of pages so that every page will be loaded from the server but this is not a good solution! if anyone can help me out with the jscript code to disable the back button......once the user log's out,then i could enable caching of the web pages and yet have security!help.......anybody!

You can't disable the back button, just like you can't disable the file menu. You can however either manipulate the history object to effectively render the back button useless, or close the window - thereby rendering the whole history a moot point.
