I have created two Facebook canvas apps. I am having problems with people accessing the apps. In the app settings you must enter:
Canvas URL Secure Canvas URL
Secure Canvas URL wont accept HTTP links but only HTTPS. When some of my users go to my app link like http://apps.facebook.com/my_app Facebook automatically redirects them to https://...
Canvas app content is loaded from my server which is only accessible via HTTP. The users which are redirected to https://apps.facebook.com/my_app then can not load my app since Facebook canvas wants to load content from my server via HTTPS. How do I solve this, without enabling SSL on mu server?
And not all users are redirected to https://apps.fa...? How is this handled?
Basically, you must provide https support. At the moment, you can still leave the Secure Canvas URL field empty to avoid doing so, but it will be required starting October 1st.
