How to clear browsers (IE, Firefox, Opera, Chrome) history using JavaScript or Java, except clearing it from browser itself?
回答1:
The document.location data in browsers is generally inaccessible to scripts, because allowing access would give any given site access to your entire browsing history. At most you can do a few simple manipulations, like "go to history entry #37" or "go back one page". But you can't do "what was the address of the page in history entry #23".
Most banking sites will use javascript links to prevent a click history from being built up. They'll do document.location.replace" to kill the last history entry (the current page) and replace it with the address of a new page. It in effect removes the "back" option to go back a page, because the previous page (as far as the browsing history is concerned) is now the new page.

In short it's not possible, sandboxing prevents browsers and the scripts/applets they run to modify or even create any files except for a few narrow cases. Javascripts and Java applets being allowed to clear other websites cookies or site content in your cache would not be desirable.

There's no way a browser will let you clear its cache. It would be a huge security issue if that were possible
What you can do is to tell it not to cache your page, by sending the appropriate headers or using these meta tags:
<meta http-equiv='cache-control' content='no-cache'>
<meta http-equiv='expires' content='0'>
<meta http-equiv='pragma' content='no-cache'>
I would like to point out that if you are working with sensitive data you should be using SSL. If you aren't using SSL, anyone with access to the network can sniff network traffic and easily see what your user is seeing.
Using SSL also makes some browsers not use caching unless explicitly told to. See this question.Will web browsers cache content over https

But if you want to clear the acutally page you can use:
$(function () {
//replace() does not keep the originating page in the session history,
document.location.replace("/Exercises#nocache"); // clear the last entry in the history and redirect to new url
