I try to clear the chrome browser cache using Add-ons. I am developing as a site using JSP with java, I need to clear the browser cache for the security reason. I tried many ways to clear the cache but none seems to work. Any ideas? Please let me know..

There's no waya browser will let you clear its cache. It would be a huge security issue if that were possible. This could be very easily abused - the minute a browser supports such a "feature" will be the minute I uninstall it from my computer.
有没有办法浏览器会让你清除缓存。如果可能的话，这将是一个巨大的安全问题。这很容易被滥用 - 浏览器支持这种“功能”的那一刻就是我从计算机上卸载它的那一刻。
What you can do is to tell it not to cache your page, by sending the appropriate headers or using these meta tags.
您可以做的是通过发送适当的标头或使用这些元标记来告诉它不要缓存您的页面。

- call
window.location.reload(true)for a ctrl+F5 from script. - In the new version of browsers
Cache.delete() - in meta tag
window.location.reload(true)从脚本中调用ctrl+F5。- 在新版浏览器中
Cache.delete() - 在元标记中
<meta http-equiv='cache-control' content='no-cache'>
<meta http-equiv='expires' content='0'>
<meta http-equiv='pragma' content='no-cache'>
- in jQuery
$('html[manifest=saveappoffline.appcache]').attr('content', '');
- 在 jQuery 中
$('html[manifest=saveappoffline.appcache]').attr('content', '');
