I may be working on a site that addresses domestic violence. (Possible class project)

If you look here: http://www.wscadv.org/

There is an "escape button" for people who may be on a public computer or may be at home with their abuser. (This is not my site- just one I am researching) The problem with it is that while it does close, and open a new window to s site that is "innocent" - the back button will immediately take anyone who looks back to the abuse site.

Is there a way to disable the back button when this link is clicked? I'd like the original site to be completely closed.

Thanks,

Ev

Please see the FAQ entry How can I make a button that closes the window?

Maybe you could use JS to "link" to the new page (for those that are JS-enabled, of course). If you use location.replace instead of the usual location.href, the old URL is replaced by the new on in the browser's history.

But none of this solves your problem. Daddy can click the back button twice and get to the page previously viewed which likely is on the anti-abuse site too. And there's always the cache.

While many browsers can be run in kioskmode where it's possible to disable a lot of things, it can be pretty complicated. If the kid is in a risky situation, I wonder if it wouldn't be better to use something like Off By One. It keeps cache and history in memory, nothing is written to disk. When the browser is closed, it's gone. You can run it from a USB stick or even a floppy. It won't make pages look pretty though.

IIRC encrypted pages (using the https:// protocol) are not cached, is that correct?

BTW the Escape button shows up to the left in Opera9, concealing the content on some pages.

Just an FYI:

Thank you all - each answer was good info in it's own way. The close button was the best option in the end, though not ideal - there's a catch to everything.
