HTTP::Daemon::Simple - simple implementation of http server |
| 6 |
|
| 7 |
=head1 DESCRIPTION |
| 8 |
|
| 9 |
This class is abstracted from C<httpd.pl> to encapsulate different HTTP server |
| 10 |
related tasks (single or multi user model, encryption etc.) |
| 11 |
|
| 12 |
This is small http server, based on C<HTTP::Daemon> which is designed |
| 13 |
for single-user use (on laptop for example) via loopback. |
| 14 |
|
| 15 |
It doesn't provide any authentification or authorisation, and it can handle |
| 16 |
just one request at the time, so it's not suted for public-facing sites, |
| 17 |
even if you don't care about security of your mailboxes. |
| 18 |
|
| 19 |
It's very much based on based on post available at: |
| 20 |
L<http://www.mail-archive.com/libwww@perl.org/msg04750.html> |
