563	improvement proposed for ngx_http_perl_module: add header_in_set	David Coutadeur		"Hi,

I would like to set input headers in perl module, but I realized that the functionnality was not present.
It can be useful, for example for this proxy configuration example:

{{{
server {
    listen *:8080;
    server_name test.example.com;

    # SSO protection
    location / {
        authn_request /auth;
        proxy_pass http://backend.lan/;
    }
    set $redirectURL """";

    location = /auth {
        perl My::Handler;
    }
}
}}}

With this example, the Handler perl module could have the directive:
$r->header_in_set('key', 'value');
so that the final backend could use this header.

It does not seems much complicated, just a modification of nginx.xs could be sufficient. The functionnality can be found for example in HttpHeadersMoreModule for example (http://wiki.nginx.org/HttpHeadersMoreModule#more_set_input_headers)"	enhancement	closed	minor		nginx-core	1.5.x	wontfix			Linux debian-wheezy-64-lemon 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux	"nginx version: nginx/1.6.0
