Issue w/ nginx in hybrid static/php load balancer scenario

[Mike Javorski]

I have nginx set up as a load balancer in front of two machines
running fastcgi/php, and nginx for static content. The desired goal is
to have all php pages (including the site index pages of .*/index.php)
processed by the fastcgi/php upstream, and everything else provided by
the static servers. The following is what I have and what I believe
should have worked, but it appears to run all directory paths via the
static rule, rather than the php rule which matches the index.

To sum up:
/ -- via static system (WRONG)
/index.php -- via fastcgi/php system (RIGHT)
/blah/ -- via static system (WRONG)
/blah/index.php -- via fastcgi/php system (RIGHT)

nginx version is 0.6.25, Help! :-)

My Config File (the relevent bits anyway):
---------------------------------------------------

http {
    upstream  static-pool {
        server  192.168.7.40:80;
        server  192.168.7.41:80;
    }

    upstream php-fcgi-pool {
        server  192.168.7.40:7000;
        server  192.168.7.41:7000;
    }

    server {
        listen  80;
        root    /website/htdocs;
        index   index.php;
        fastcgi_index   index.php;
        include     /etc/nginx/fastcgi_params;

        location / {
            proxy_pass http://static-pool/website/htdocs/;
        }

        location ~ \.php$ {
            fastcgi_pass    php-fcgi-pool;
        }
    }
}
