Content-Length
Messing around with those could expose various request smuggling attacks, so the browser always uses its own values. There's no need or reason to try to set the request length, as the browser can do that accurately from the length of data you pass to send()."
I can reproduce this problem with Google Chrome. However, using the "rivate Mode" of google chrome, logging in to facebook in private mode, then using the login with facebook option works.
What does not work is the following: The login via facebook when not logged into facebook before. This causes the "choose if you want ag to spam your timeline" option to appear, and after that screen, the url "http://armorgames.com/auth/facebook/init" loads forever, in Chrome private mode and in internet explorer.
Another thing: I tried to register a non-facebook-ag-account, which doesn't work either. Trying to go to "http://armorgames.com/register" with any browser redirects to "https://armorgames.com/login" eventually, not giving a possibility of registering anything.
@Ferret After reloading without cache (ctrl+shift+r), the facebook button still does nothing on click (no output in log console or network log in chrome)
