86 | =head1 DESCRIPTION |
bf2bce67 |
87 | |
1a776a0c |
88 | In order for L<Catalyst::Plugin::Session> to work the session ID needs to be |
89 | stored on the client, and the session data needs to be stored on the server. |
bf2bce67 |
90 | |
1a776a0c |
91 | This plugin stores the session ID on the client using the cookie mechanism. |

127 | |
128 | =over 4 |
129 | |
130 | =item cookie_name |
131 | |
132 | The name of the cookie to store (defaults to C<session>). |
133 | |
41b4b15c |
134 | =item cookie_domain |
135 | |
136 | The name of the domain to store in the cookie (defaults to current host) |

140 | =head1 CAVEATS |
db1cda22 |
141 | |
142 | Sessions have to be created before the first write to be saved. For example: |
143 | |
144 | sub action : Local { |
145 | my ( $self, $c ) = @_; |
146 | $c->res->write("foo"); |
147 | $c->session( ... ); |
148 | ... |
149 | } |
150 | |
151 | Will cause a session ID to not be set, because by the time a session is |
152 | actually created the headers have already been sent to the client. |
