=head1 DESCRIPTION |
| 20 |
|
| 21 |
This is small http server, based on C<HTTP::Daemon> which is designed |
| 22 |
for single-user use (on laptop for example) via loopback. |
| 23 |
|
| 24 |
It doesn't provide any authentification or authorisation, and it can handle |
| 25 |
just one request at the time, so it's not suted for public-facing sites, |
| 26 |
even if you don't care about security of your mailboxes. |
