HTTP Headers to Disable Caching in Firefox

It took me ages to find this:

Cache-control: no-cache
Cache-control: no-store
Pragma: no-cache
Expires: 0

To alter headers in the IIS7 GUI go HTTP Response Headers. It won't allow you to add two headers of the same name so either add no-cache,no-store or you can set no-cache by expiring web content immediately in Set Common Headers at the top right and add Cache-control: no-store manually.
