I think I saw a document on CCO to describe how to do this but i cant find it.
In my prod environment I am operating multiple URL's. They all use a single content rule.
So in actual fact I believe that my content rule needs to use wildcards.
i want to use wildcards for the above so that I only have a single content rule and the config remains short
where * is any character.
I then have a backend web server which uses host headers to determine what site / content to display in the browser.
