GEOIP context problem

[adamchal]

This really sucks.  It'd be MUCH better if you could simply inherit the
fastcgi_param.  I've now come across this a bunch of times with
different projects.  It'd be nice for example to pass DEBUG 1 or DEBUG 0
to the fastcgi handler.

The documentation makes sense after you read it a bunch of times, but at
first read, it makes it seem like you can inherit portions of
fastcgi_param.
