Browse Source 
Fix referer spoofing not working for certain fc2.com image URLs.

Spoofing the referer like this redirects to an HTML error page:

* curl -H "Referer: http://wwwew.web.fc2.com" http://wwwew.web.fc2.com/e/405.jpg

Spoofing it like this works:

* curl -H "Referer: http://wwwew.web.fc2.com/e/405.jpg" http://wwwew.web.fc2.com/e/405.jpg
