out(options = "text/html") public

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 #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" }
