Description
We have $upstream_http_$HEADER so why not a fastcgi equivalent?
With this we can set dynamic cache keys which is very useful for many PHP applications which serve up different content for the same page (i.e. languages and skins but NOT sessions).

As these variables are only available with a response, there is no much sense in using them in fastcgi_cache_key - as cache key is evaluated before a request is sent to a backend.
Note:
See TracTickets
for help on using tickets.
The $upstream_http_* variables are generic, and represent response headers as returned by a backend with all backend protocols, including fastcgi.
