to www or not to www, creating your Facebook App
It turns out you will need to add www to your site url used when creating a Facebook book application, otherwise it won’t work. You’d think their system would compensate for the presence or absence of www, but then again it makes sense because you might have a subdomain. This makes sandbox testing a little challenging (do you create another app for your real app?). Nonetheless, we posted this because we think they should program for the case someone hurriedly signs up for creating a Facebook application and they exclude the beginning www.
