Since it is supposed to be transparent, is there a way to tell whether a  
website I am visiting is using RoR to serve its content?

I just got the HTTP header from my localhost Rails app…  
and it is nothing special:

HTTP/1.1 200 OK  
Connection: close

kinda childish but you’ll be surprised how much it works - in the folder  
public/images there is a rails.png picture that comes with the app (the  
second you create it). no one really seems to delete this useless  
picture, and if you try and search for it in the url and it comes up, it  
is probably (hmmm…yea, almost a sure thing) that it is a rails app.  
but it aint a god-given truth.

try adding a “/images/rails.png” to the domain name and see if you get  
the pic or no. it’s nothing certain, but i’m not sure if there is a  
certain way. anyway. ex -
