One thing i just noticed. root is defined until after that snippet  
above.
is that an issue?


Config is spread across multiple files.

Here is the best bits:

/ah/sites/colon365.co.uk/conf/nginx.conf:

server
{
   listen 208.113.69.210;
   server_name colon365.co.uk;
   server_name www.colon365.co.uk;

   include /ah/sites/colon365.co.uk/conf/nginx/base;
   include /ah/sites/colon365.co.uk/conf/nginx/maintenance;
   include /ah/sites/colon365.co.uk/conf/nginx/fake-homepage;

   access_log /var/log/ah/colon365.co.uk.log combined;
   include /ah/conf/nginx/www-shared;
}

/ah/sites/colon365.co.uk/conf/nginx/base:

set $base /ah/sites/colon365.co.uk;

--

/ah/conf/nginx/www-shared:

include /ah/conf/nginx/root;
include /ah/conf/nginx/favicon;
include /ah/conf/nginx/standard-expire;
include /ah/conf/nginx/unsub-aliases;
include /ah/conf/nginx/hackersafe;
include /ah/conf/nginx/historical;
location /
{
   if ( !-e $request_filename )
   {
     expires -1;
     proxy_pass http://mod_perl;
     break;
   }
}


--

/ah/conf/nginx/root:

set $root $base/public;
root $root;
