How to check for headers

Hello,

How would you check for sth like HTTP:Accept-Language? and in general
all
headers? if it is equal to some value, empty or etc. Apache would allow
this
to be checked in a notation similar to the following inside a
mod_rewrite
config:

%{HTTP:Accept-Language}

Is there a similar variable to be used in nginx config?

variables are at
http://nginx.org/en/docs/http/ngx_http_core_module.html#variables

“map” is at http://nginx.org/r/map

“if” is at http://nginx.org/r/if

Be aware of when you shouldn’t use “if” inside “location”, such as is
written at http://wiki.nginx.org/IfIsEvil

Depending on what exactly you want to do, frequently “map” can be used
instead of “if”.
