[Mongrel] Append Mongrel port after HTML

[Michele]

Hi,

I'm trying to debug an issue I'm having with an app where certain  
requests fail but work after a refresh which led me to think it might  
be a problem with only one Mongrel instance out of the bunch.

So I was wondering if there's an easy way (i.e. without having to  
manually patch Mongrel) to append a comment at the end of the pages'  
HTML with something like the PID or port so I can track which instance  
served the request.

Thanks for your help!
