How to stop a Safari iOS webpage from loading cached pages after adding to the home screen?

I added the site to the main screen of iOS. If the download opens a website from the iOS home screen, it seems to always load the cached page. Even if I refresh the page or delete the page completely, it still loads the original version.

It will load the updated page if I open the site directly from iOS Safari, and not by clicking the icon on the main screen.

The site is hosted on Apache under the control of Ubuntu 11.10.

I added the following inside

and added

to make it load the updated page.

I also tried clearing the cache and cookies and history from Safari settings from iOS, as well as restarting the ipad and nothing works.

Please help ~!
