Facebook Application Redirect Loop after authentication

I've encountered this problem while using the facebook c# sdk v4.2.1:

After allowing the app, a user using a IE browser without flash being installed will go on a infinite redirect authentication loop.

At first i thought it was a cookie 开发者_运维知识库problem , until i tested on another computer and realised that both of the computers had no flash installed.

Has anyone encountered this problem before? I know for sure i've encountered alot of problems that using the official facebook javascript sdk to authenticate users on IE without flash.

I would appreciate if anyone found a solution to this problem can answer this question.

Would you please edit you Facebook settings on Facebook i had the same problem before and i edit the settings on the advanced tap and it works :)

hope that works .

I just had this problem when reviving an older facebook app. I fixed it by enabling "signed_request for Canvas" in the Advanced settings tab on for the app on facebook.

Flash shouldn't be the problem. Did you install the Facebook handler in your web.config?

Also it sounds like you aren't being properly authenticated. You might want to sniff with something like Fiddler and see what is happening.
