Unable to access facebook

Hello,

Our system blocks facebook but a request was made to give one of our users access to it which we did but he can't access it still.
When we gave him access, he can now view the webpage but as soon as he started creating a login and tries it, he's getting a proxy error.
Here's the comment from our Network Admin "https://*.facebook.com/*  & https://login.facebook.com/* is allowed in proxy server. I have even tried to access by adding PC to the rule. Still the same error. I am not sure why the proxy server is blocking it. It is possible it is trying to go another site that is not allowed but not reporting it with the error message."

If the user can view the facebook website after we gave him access but getting an error when he logs in, could it be that it's going to a different address to authenticate after he logs in??

Not sure what ability you have to write rules, but you might try allowing *://*.facebook.com/*.  This would wild card any connection of any type dealing with facebook.  

It might help us to know what kind of device(s) you are going through and do you have more than one security device that could be causing the issue. Is it possible that there are IE settings that might also come into play?

With the setup we have here, putting in a similarly formatted rule would work.

Another possibility would be group definitions.  Do you define access by groups and could this person be in more than one group.  Some systems work on the less restrictive settings of multiple groups while others work on the more restrictive settings.
Facebook doesn't use https.

It redirects back to the normal http port when you try access it with https, so.. while you may have given your user access to https://*.facebook.com, once the Facebook webserver redirects to http://*.facebook.com, your user's access breaks.

What proxy are use using to allow/deny access to these sites?

Does it work after you've logged in?  

I can connect to https://www.facebook.com and it shows me the login page, but the moment I am logged in I am redirected to http://www.facebook.com/home.php? which would cause an ACL to break if it only permitted https://*.facebook.com.
