59 | Finalize body. Prints the response output as blocking stream if it looks like |
60 | a filehandle, otherwise write it out all in one go. If there is no body in |
61 | the response, we assume you are handling it 'manually', such as for nonblocking |
e37f92f5 |
62 | style or asynchronous streaming responses. You do this by calling L<\write> |
4e6e0ab2 |
63 | several times (which sends HTTP headers if needed) or you close over C<$response->write_fh>. |
e37f92f5 |
64 | |
65 | See L<Catalyst::Response\write> and L<Catalyst::Response\write_fh> for more. |
