out

        # CGI.out

(from ruby core)
---
    cgi.out(content_type_string='text/html')
    cgi.out(headers_hash)

---

Print an HTTP header and body to $DEFAULT_OUTPUT ($>)

`content_type_string`
:   If a string is passed, it is assumed to be the content type.
`headers_hash`
:   This is a Hash of headers, similar to that used by #http_header.
`block`
:   A block is required and should evaluate to the body of the response.


`Content-Length` is automatically calculated from the size of the String
returned by the content block.

If `ENV['REQUEST_METHOD'] == "HEAD"`, then only the header is output
(the content block is still required, but it is ignored).

If the charset is "iso-2022-jp" or "euc-jp" or "shift_jis" then the
content is converted to this charset, and the language is set to "ja".

Example:

    cgi = CGI.new
    cgi.out{ "string" }
      # Content-Type: text/html
      # Content-Length: 6
      #
      # string

    cgi.out("text/plain") { "string" }
      # Content-Type: text/plain
      # Content-Length: 6
      #
      # string

    cgi.out("nph"        => true,
            "status"     => "OK",  # == "200 OK"
            "server"     => ENV['SERVER_SOFTWARE'],
            "connection" => "close",
            "type"       => "text/html",
            "charset"    => "iso-2022-jp",
              # Content-Type: text/html; charset=iso-2022-jp
            "language"   => "ja",
            "expires"    => Time.now + (3600 * 24 * 30),
            "cookie"     => [cookie1, cookie2],
            "my_header1" => "my_value",
            "my_header2" => "my_value") { "string" }
