|
HTTP::Daemon::Simple - simple implementation of http server |
| 6 |
|
|
|

|
|
=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: |
