When building a Facebook tab application the first page receives the signed request, my question is what is the best practice to handle the secondary requests. You could save the related information in a cookie to have it on the secondary requests but that seems a little unsecured to me.
I am just curious what is the recommend way to handle this basic situation.
The signed request is just an intermediate step to getting the access_token and userid.
I put the access token into Session, and I also encrypt it and save it in a cookie. Facebook app development has taught me to go belt-and-suspenders when it comes to authentication.
