Hi
It is something I am just about to write into a PHP script I am finishing off (I think I will call it Content Magic). You can see a page generated by it at:
www.chippingcampdenbaptistchurch.org.uk
(this is only a test page, so don't be surprised if the links are not working, or go to broken pages).
How I propose to go about it is this.
First, any PHP generated should have head body etc, and it is not beyond the wit of man to make sure it does.
In the head, put a meta tag to re-direct the robots, OR use the robots.txt file to re-direct them.
Where to? A special html page that dumps the content of the database, roughly formatted (minus any email addresses to avoid spam).
In that html page, have a java re-direct, so jo public doesn't get to see it. Coz it's java, you can make sure the robots doesn't understand it. If you are concerned a user with java disabled can still read it, put a java test in first usinga bit of php and redirect anyway. Or whatever.
