Hi guys!
i just switched to nginx. I can't handle to define a virtualhost which serves both site.xxx and www.site.xxx.
Here is my nginx.conf:
- if I try to access site.xxx I get the index.php as normal
- if I try to access www.site.xxx I get a binary file to download (which is the index.php)
- I noticed that loggin in site.xxx and then going to site.xxx/whiceverpage gives me the right page as logged, instead loggin in site.xxx and then going to www.site.xxx/whiceverpage gives me the login page as the session isn't the same created with the first login.

What the hell am I doing wrong?
Thanks for the help guys.
