If you set Cache-Control: "no-cache, no-store, must-revalidate" to http headers the page won't be cached in back-forward cache.

Firefox also considers event handlers on beforeunload event as a signal to not store page in BFC, but Safari ignores such handlers, so it's better to set correct http headers to indicate the nature of the page content (cacheable or variable)
