I've made a website, which relies on Facebook OAuth in order for the user to participate in a competition.
The canvas URL within Facebook differentiates between https://www.mycompetition.com/ and https://mycompetition.com
Our server is set up to receive both entries, but if I enter the site using www, Facebook complains that the URL doesn't match when authorizing.
Do you know how to make Facebook accept both entries?
Solved, by the way. The webserver now contains two websites. The first contains the website, the second one just redirects to the first one, using JS. Easy :)
