Re: [Cppcms-users] Custom Headers in request()

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

Hello,

I think I answered this question ones. But anyway

CppCMS uses CGI based API, in order to read some
header like X-Foo-Bar you need to read environment
variable HTTP_X_FOO_BAR (See [1]) However
some web servers do not pass all headers for example
nginx passes only headres defined explicitly in fastcgi
configuration, so the behavior may vary between the servers.

Cppcms has API for it cppcs::http::request::getenv()
see [2]. So basically all you need is to call getenv()
for CGI variable.

    Meta-Variables at http://www.ietf.org/rfc/rfc3875
