46 | =head1 DESCRIPTION |
47 | |
910410b8 |
48 | This is the Catalyst Response class, which provides methods for responding to |
46372e65 |
49 | the current client request. The appropriate L<Catalyst::Engine> for your environment |
50 | will turn the Catalyst::Response into a HTTP Response and return it to the client. |

54 | =head2 $res->body(<$text|$fh|$iofh_object) |
e060fe05 |
55 | |
56 | $c->response->body('Catalyst rocks!'); |
06e1b616 |
57 | |
46372e65 |
58 | Sets or returns the output (text or binary data). If you are returning a large body, |
59 | you might want to use a L<IO::FileHandle> type of object (Something that implements the read method |
60 | in the same fashion), or a filehandle GLOB. Catalyst |
61 | will write it piece by piece into the response. |

65 | Shortcut for $res->headers->content_encoding. |

67 | =head2 $res->content_length |
b5176d9e |
68 | |
910410b8 |
69 | Shortcut for $res->headers->content_length. |

71 | =head2 $res->content_type |
b5176d9e |
72 | |
910410b8 |
73 | Shortcut for $res->headers->content_type. |

75 | This value is typically set by your view or plugin. For example, |
76 | L<Catalyst::Plugin::Static::Simple> will guess the mime type based on the file |
77 | it found, while L<Catalyst::View::TT> defaults to C<text/html>. |
78 | |
b5ecfcf0 |
79 | =head2 $res->cookies |
fc7ec1d9 |
80 | |
910410b8 |
81 | Returns a reference to a hash containing cookies to be set. The keys of the |
82 | hash are the cookies' names, and their corresponding values are hash |
83 | references used to construct a L<CGI::Cookie> object. |
fc7ec1d9 |
84 | |
85 | $c->response->cookies->{foo} = { value => '123' }; |
86 | |
910410b8 |
87 | The keys of the hash reference on the right correspond to the L<CGI::Cookie> |
88 | parameters of the same name, except they are used without a leading dash. |
89 | Possible parameters are: |
