In the 2010 road map, with the ability to extract particular cookies, do 
you reckon we could do anything to make this work?  So, we'd set a 
cookie called "RenderType", and then Varnish would key on that cookie 
value?  In the short term, can we set the hash to be a combination of a 
cookie value and host and URL?
