window.history.back() shows “Document Expired” pag

问题:

Client is asking for the ability for users to go back to a page full of search results after clicking on a result. Right now it's a simple jQuery call:

$('a.detail-back-button').on('click', function(evt) {
    evt.preventDefault();
    window.history.back();
});

This shows a "Document Expired" page in Firefox, however. I know it's there for security, but the client wants this implemented anyways. I've done some searching around and I've found a php solution to the problem...

session_cache_limiter('private_no_expire')

...but this is a Django-based web site. Are there any other solutions?

The solution below works but only for browsers that aren't IE. IE8/9/10 doesn't seem to re-request the previous page. Is there an IE workaround?

回答1:

This has to do with the by definition non-idempotent nature of POSTed requests. I.e. a POST is an action which has an effect, and is thus unsafe to repeat. To prevent this from happening accidentally, some browsers show a placeholder page with a confirmation message before resubmitting the original form.

The most reliable solution -possibly the only one- is to submit your form using the GET method instead, which makes sense anyway.
