server {
listen 80;
server_name www.site.com;
rewrite ^ http://site.com$request_uri?;
}
server {
listen 80;
server_name site.com;
access_log /var/log/nginx/site.com_access.log;
error_log /var/log/nginx/site.com_error.log;
root /var/www/citysites/site.com/htdocs;
index index.php;

location ~* \.(js|jpeg|jpg|gif|png|swf)$
{
access_log off;

}

location ~ ^/(?!js/|image/upload).+\/$
{

}

location /
