Catalyst::Engine::HTTP::Prefork - High-performance pre-forking Catalyst engine
This engine is designed to run as a standalone Catalyst server, without
requiring the use of another web server. Its goals are high-performance,
HTTP/1.1 compliance, and robustness. It is also suitable for use as a
faster development server with support for automatic restarting.
This engine is designed to replace the Catalyst::Engine::HTTP::POE engine,
which is now deprecated.
This engine supports the same restart options as Catalyst::Engine::HTTP.
The server may also be restarted by sending it a HUP signal.
This engine fully supports the following HTTP/1.1 features:
Chunked body data is handled transparently by HTTP::Body.
By setting the Transfer-Encoding header to chunked, you can indicate you
would like the response to be sent to the client as a chunked response. Also,
any responses without a content-length will be sent chunked.
Browsers sending any number of pipelined requests will be handled properly.
Keep-alive is supported for both HTTP/1.1 (by default) and HTTP/1.0 (if a
Connection: keep-alive header is present in the request).
Additional options may be passed to the engine by modifying
yourapp_server.pl to send additional items to the run() method.
The minimum number of servers to keep running. Defaults to 5.
The minimum number of servers to have waiting for requests. Minimum and
maximum numbers should not be set too close to each other or the server will
fork and kill children too often. Defaults to 2.
The maximum number of servers to have waiting for requests. Defaults to 10.
The maximum number of child servers to start. Defaults to 50.
Restart a child after it has served this many requests. Defaults to 1000.
Note that setting this value to 0 will not cause the child to serve unlimited
requests. This is a limitation of Net::Server and may be fixed in a future
This enables Net::Servers leave_children_open_on_hup option. If set, the parent
will not attempt to close child processes if the parent receives a SIGHUP. Each
child will exit as soon as possible after processing the current request if any.
This passes through to Net::Servers pid_file option. If set, the pidfile is
written to the path. Default is none. This file is not removed on server exit
This option passes through to Net::Server and also sets the setsid option to
