[Nitro] Nitro on Apache

fcgi is not worth the trouble.

I suggest running Nitro standalone and using Apache's reverse proxying 
features as a front-end.

With Apache 2.2 there's mod_proxy_balancer, which is *very* nice.

With both Apache 2.0 and 2.2 you can use mod_rewrite like this:

<VirtualHost *:80>
  ServerName robmela.com
  ServerAlias www.robmela.com
  ServerAlias blog.robmela.com
  RewriteEngine On
  RewriteRule ^/admin(.*) https://nb.robmela.com/admin$1 [L,R]
  RewriteRule ^/(.*)$1 [L,P]
  #ProxyRequests off
  #ProxyPass /
  #ProxyPassReverse /
  #ProxyPreserveHost on

There is one caveat for heavily loaded sites or applications with 
long-running pages... which I'll get into later as I'm writing an Apache 
/ Mongrel how-to that covers some gotchas.
