Ensuring "Always Check for new Pages" in Internet Explorer

We are having a problem with some of our web services in our applications. Basically, Internet Explorer is caching some of the XML and so the apps are not updating. I have been asked by some of our developers to see if there is a way, either via vbscript that I can add to the login script or through Group Policy, to ensure that the setting:

Internet Options -> General -> Browsing History -> Settings -> Check for newer versions of stored pages

is set to Everytime I visit the webpage.

I have been unsuccessful so far to find a way to manipulate this through script or through modifying a registry key. Any help in this would be greatly appreciated. I need to cover IE 6,7, & 8 preferably.

Thanks for 开发者_如何学编程your help.

The registry key is named SyncMode5, you'll find it in: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

You can also configure this setting using the IEAK.

But Slaks is correct that the proper fix is to have the server send correct caching headers.
