* On some sites, multiple domains or subdomains may point to the same site.
* For instance, example.com may redirect to foo.example.com.  In that case, 
* the browser may confuse the cookies between the two domains, resulting in 
* an inability to log in.  In that case, uncomment the line below and set 
* it to the more generic domain name.  For instance, .example.com is more
* generic than .foo.example.com.  Remember the leading period on the domain
* name, even if you wouldn't type it in your browser.
