Issue title: Fastly not working.
 Issue body: Hello all

We installed and configured the extention plus the fastly options. In stat page, on fastly website, no requests are shown, and when sometimes they are, they are all pass. 

Note that our server have also varnish, plus we use ssl. 

Any advice?
