Re: [Cppcms-users] Get HTTP Headers of Request

[Artyom <art...@ya...>]

According to CGI specifications you should use 

cppcms::http::request::getenv with "HTTP_WHICH_HEADER"
as parameter

Note, it is up to web server to provide such variable.

See <http://tools.ietf.org/html/rfc3875#section-4.1.18>

Note: some web servers(like Niginx) require a list of specific
headers to be passed explicitly, others may filter them.

So basically you need: request().getenv("HTTP_WHICH_HEADER");
