10.2 Keeping a Page Out of the Browser History
NN 3, IE 4
You want to remove the current page from
the browser history so that the Back button does not take the user
back to the current page after a script navigates to some other page.
Navigate to the next page via the location.replace(
The capability of keeping a page out of the
browser's history can come in handy when your site
contains a page that include automatic forwarding under script
control. Recipe 5.10 is a typical situation that benefits from
keeping a temporary page out of the history. If the user reaches the
real home page, a press of the browser's Back button
normally brings the user back to the temporary page, and the user is
essentially trapped in an infinite loop from which escape can only
occur by going forward.
You can also use this technique if you do not want a user to come
back to a form after submitting it. But in this case, you must
assemble the form data yourself, appending it to the URL string
passed with the replace(
) method. The page returned from your CGI
program replaces the form page in the browser history. Be aware,
however, that this works only for form submissions that can be
accomplished with the GET method, rather
than the POST method. Invoking the location.replace(
) method causes the browser to request a page through a GET
method just like a regular web page.
