SYNOPSIS

  with 'CGI::Header::PSGI';

  sub crlf { $CGI::CRLF }

VERSION

This document refers to CGI::Header::PSGI 0.01.

DESCRIPTION

This module is a role to generate PSGI response headers.

REQUIRED METHODS

Your class has to implement the following methods.

$query->charset

Returns the character set sent to the browser.

$query->self_url

$query->cache

$query->no_cache (optional)

$query->crlf

Returns the system specific line ending sequence.

METHODS

By using this module, your class is capable of following methods.

($status_code, $headers_aref) = $query->psgi_header( %args )

Works like CGI.pm's header(), but the return format is modified. It returns an array with the status code and arrayref of header pairs that PSGI requires.

Unlike header(), this method doesn't update charset().

($status_code, $headers_aref) = $query->psgi_redirect( %args )

Works like CGI.pm's redirect(), but the return format is modified. It returns an array with the status code and arrayref of header pairs that PSGI requires.
