NAME
Catalyst::Engine::HTTP::Prefork - High-performance pre-forking Catalyst engineSYNOPIS
CATALYST_ENGINE='HTTP::Prefork' script/yourapp_server.pl
DESCRIPTION
This engine is designed to run as a standalone Catalyst server, without requiring the use of another web server. It's 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.
RESTART SUPPORT
This engine supports the same restart options as Catalyst::Engine::HTTP. The server may also be restarted by sending it a HUP signal.HTTP/1.1 support
This engine fully supports the following HTTP/1.1 features:Chunked Requests
Chunked body data is handled transparently by HTTP::Body.Chunked Responses
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.Pipelined Requests
Browsers sending any number of pipelined requests will be handled properly.Keep-Alive
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).CUSTOMIZATION
Additional options may be passed to the engine by modifying yourapp_server.pl to send additional items to the run() method.min_servers
The minimum number of servers to keep running. Defaults to 5.min_spare_servers
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.max_spare_servers
The maximum number of servers to have waiting for requests. Defaults to 10.max_servers
The maximum number of child servers to start. Defaults to 50.max_requests
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 version.restart_graceful
This enables Net::Server's 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.pidfile
This passes through to Net::Server's pid_file option. If set, the pidfile is written to the path. Default is none. This file is not removed on server exitbackground
This option passes through to Net::Server and also sets the 'setsid' option to true.AUTHOR
