There is a class HeaderHash but as far as I realize by inspecting the code, 
it's just used to create the response, and not to store the request headers.

Do I miss something?

Thanks a lot.

How to get the request headers from "env" hash?

[Iñaki Baz Castillo]

Hi, I'm just starting with Rack by testing some simple examples.

For now I just would like to know how to get the request headers, as this info 
is not present in "env" hash which just contains:

HTTP_HOST => 127.0.0.1:9292
HTTP_ACCEPT => text/html, image/jpeg;q=0.9, image/png;q=0.9, text/*;q=0.9, 
image/*;q=0.9, */*;q=0.8
SERVER_NAME => 127.0.0.1
rack.url_scheme => http
REQUEST_PATH => /
HTTP_USER_AGENT => Mozilla/5.0 (compatible; Konqueror/4.3; Linux 2.6.28-15-
generic; es, en-GB, en-US, en) KHTML/4.3.0 (like Gecko)
rack.errors => #<IO:0x7f3c3beabab8>
HTTP_ACCEPT_LANGUAGE => es, en-GB, en-US, en
SERVER_PROTOCOL => HTTP/1.1
rack.version => 01
rack.run_once => false
SERVER_SOFTWARE => Mongrel 1.1.5
PATH_INFO => /
REMOTE_ADDR => 127.0.0.1
SCRIPT_NAME =>
rack.multithread => true
HTTP_VERSION => HTTP/1.1
rack.multiprocess => false
REQUEST_URI => /
HTTP_ACCEPT_CHARSET => utf-8, utf-8;q=0.5, *;q=0.5
SERVER_PORT => 9292
REQUEST_METHOD => GET
QUERY_STRING =>
rack.input => #<StringIO:0x7f3c39aaecc8>
HTTP_CONNECTION => Keep-Alive
HTTP_ACCEPT_ENCODING => x-gzip, x-deflate, gzip, deflate
GATEWAY_INTERFACE => CGI/1.2


env["rack.input"] contains a IO object with the request body, but I don't see 
in the above hash how to get the request headers (any header).

Thanks for any help.
