Although this isn’t directly rails related, I am hopefull that I can get  
some advice here… 🙂

I can’t seem to find a way to configure nginx with the standard modules  
included to proxy\_pass based off a custom html header attribute. The  
only possibility I came up with was to write a custom module in c and  
then link it into nginx.

Does anyone know of an alternative to nginx that can accomplish this or  
how to achieve this within nginx.
