I want my system to check local copies of a page against a cache I have of the same page and if they are different it won't serve the page and will automatically send me a copy of the page via email and restore it to what it should be. A way of protecting against attacks. Just 1 stage but I want to be pro-active and always be ontop of things. Chris
