Nginx rules to redirect non-WWW to WWW URL?

I have a vbulletin forum registered with the following domain:

http://studioleaks.info

Code (markup):

However the actual forum itself is located in a folder called "forums", under the "public" (nginx site root) directory. The only content that's in my site root is an under construction page, which I don't want visitors to see, so I need to make sure that all traffic redirects to:

www.studioleaks.info/forums/

Code (markup):

Until recently I was using Apache/Cpanel, with the following rule placed in an .htaccess file in my forum root:

RewriteCond %{HTTP_HOST} !^www\.studioleaks\.info
RewriteRule (.*) http://www.studioleaks.info/forums/$1 [R=301,L]

Code (markup):

This worked to make sure that, regardless of whether a visitor typed in the www or non-www version of the site root, studioleaks.info (i.e. not the forum root), that they would be redirected to the www version of the forums:

http://www.studioleaks.info/forums/

Code (markup):

I've switched to Nginx now. I have the following in my conf (some info removed for security/privacy reasons:

server {
		listen   80;
		server_name site.studioleaks.info;
		root   html;

		location / {            
            }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
        root   html;
            }
}

server {
		listen 				server-ip-address:80;
		server_name 		studioleaks.info;
		rewrite ^ http://www.studioleaks.info/forums$request_uri? permanent;
}

server {
		listen 		server-ip-address:80;
		server_name www.studioleaks.info;
		access_log 	/.../.../.../.../log/access.log;
		error_log 	/.../.../.../.../log/error.log;
		root 		/.../.../.../.../public;
		index 		index.html index.php;

Code (markup):

Note:site.studioleaks.info is my FQDN. I used this instead of localhost (using an FQDN here and as my hostname in /etc/hosts is preferable to a non-FQDN domain, or am I mistaken?

The end result is, if I type in the non-www version of 'studioleaks.info' (by itself, no /forums/), it forwards to the www version of:

www.studioleaks.info/forums/[code]
However if I type in the www version of 'studioleaks.info' (again, with no /forums/), it still loads the under construction page located at
[code]www.studioleaks.info

Code (markup):

This is a big, big problem, since the www version of studioleaks.info is my preferred URL with Google, the listing that contains my sitelinks, etc.

My question is: How do I make both the www and non-www versions of 'studioleaks.info' forward to:

www.studioleaks.info/forums/

Code (markup):

 

grrrrrr.... this is really starting to get on my nerves. I've posted this on the Nginx forums and gotten zero responses. Someone MUST know how to redirect both a www and non-www version of the same domain to the same page!

server {
		listen			184.107.161.202:80;
		server_name		studioleaks.info;
		rewrite ^		http://www.studioleaks.info/forums$request_uri? permanent;
}

server {
		listen			184.107.161.202:80 default_server;
		server_name		www.studioleaks.info;
		access_log		off;
		error_log		/log/error.log;
		root			/studioleaks.info/public;
		index			index.php index.html;

Code (markup):

I've seen examples posted with both the www and non-www versions listed in a single block, like this:

server {
        listen   80;
        server_name  example.com www.example.com;
        rewrite ^/(.*) http://www.example.com/$1 permanent;
}

Code (markup):

But when I try that it results in a redirect loop. In fact any change I make seems to result in a redirect loop. How do I fix this? How hard is it to make www and non-www both point to /forums/ under nginx?
