Description :
This is a simple standalone HTTP server. By default, it doesn\'t thread or
fork. It does, however, act as a simple frontend which can be used to build
a standalone web-based application or turn a CGI into one.
It is possible to use Net::Server classes to create forking, pre-forking,
and other types of more complicated servers; see net_server.
By default, the server traps a few signals:
* HUP
When you \'kill -HUP\' the server, it lets the current request finish being
processed, then uses the \'restart\' method to re-exec itself. Please note
that in order to provide restart-on-SIGHUP, HTTP::Server::Simple sets a
SIGHUP handler during initialisation. If your request handling code forks
you need to make sure you reset this or unexpected things will happen if
somebody sends a HUP to all running processes spawned by your app (e.g. by
\"kill -HUP < script>\")
* PIPE
If the server detects a broken pipe while writing output to the client, it
ignores the signal. Otherwise, a client closing the connection early could
kill the server.
