I have read a little about using the hosts file to block websites, and have used this method as well. But I would like to know if it is possible to have the hosts file point to a file on the local hard drive if the user visits a web site that has been entered into the host file. This way you could give a customized messaged instead of the server not found page. In some cases the user could keep trying different addresses, and different methods to get to the site maybe even finding one you haven't blocked if they didn't know it was blocked and for a good reason.
ie. 127.0.0.1\ [path to folder] \blocked.htm www.gator.com
Thanks for your time and "greater than mine" knowledge,
