=for markdown ```

=head1 DESCRIPTION

This is pure-Perl HTTP proxy server which can be run on almost every Perl
installation.

It uses L<thrall> pre-threading HTTP server if Perl supports threads or
L<starlight> pre-forking HTTP server otherwise.

It supports SSL and TLS if L<IO::Socket::SSL> is installed and IPv6 if
L<IO::Socket::IP> is installed.

It can be fat-packed and then run with any system with standard Perl
interpreter without installing other packages. See F<examples> directory for
fat-packed version of PureProxy script.

PureProxy is an application that accepts arguments of L<plackup> binary and
HTTP servers like L<thrall> or L<starlight>.

=head1 OPTIONS

=head2 --access-log

Specifies the pathname of a file where the access log should be
written. By default, in the development environment access logs will
go to STDERR. See L<plackup>. (default: none)

=head2 --daemonize

Makes the process run in the background. It doesn't work (yet) in native
Windows (MSWin32). (default: 0)

script/pureproxy.pl  view on Meta::CPAN

one, persistent connections are disabled. (default: 1)

=head2 --max-reqs-per-child

Max. number of requests to be handled before a worker process exits. (default:
1000)

=head2 --max-workers

A number of worker threads. (default: 50)

=head2 --min-reqs-per-child

If set, randomizes the number of requests handled by a single worker process
between the value and that supplied by C<--max-reqs-per-chlid>.
(default: none)

=head2 -p, --port

Binds to a TCP port. Defaults to 5000. This option is only valid for
servers which support TCP sockets.

Note: default port 5000 may conflict with AirPlay server on MacOS 12
(Monterey) or later.

=head2 --pid

Specify the pid file path. Use it with C<-D|--daemonize> option.
(default: none)

=head2 -q, --quiet

Suppress the message about starting a server.

=head2 -r, --reload

Makes plackup restart the server whenever a file in your development
directory changes. See L<plackup>. (default: none)

=head2 -R, --Reload

Makes plackup restart the server whenever a file in any of the given
directories changes. See L<plackup>. (default: none)

=head2 --socket

Enables UNIX socket support. The L<IO::Socket::UNIX> module is required. The
socket file has to be not yet created. The first character C<@> or C<\0> in
the socket file name means that an abstract socket address will be created.
(default: none)

=head2 --spawn-interval

If set, worker processes will not be spawned more than once every given
second. Also, when I<SIGHUP> is being received, no more than one worker
process will be collected every given second. This feature is useful for
doing a "slow restart". (default: none)

=head2 --ssl

Enables SSL support. The L<IO::Socket::SSL> module is required. (default: 0)

=head2 --ssl-ca-file

Specifies the path to the SSL CA certificate file which will be a part of
server's certificate chain. (default: none)

=head2 --ssl-cert-file

Specifies the path to the SSL certificate file. (default: none)

=head2 --ssl-client-ca-file

Specifies the path to the SSL CA certificate file for client verification.
(default: none)

=head2 --ssl-key-file

Specifies the path to the SSL key file. (default: none)

=head2 --ssl-verify-mode

Specifies the verification mode for the client certificate.
See L<IO::Socket::SSL/SSL_verify_mode> for details. (default: 0)

=head2 --timeout

Seconds until timeout. (default: 300)

=head2 --traffic-log

Enables L<Plack::Middleware::TrafficLog> middleware that logs detailed
information about headers and the body.

If the filename is providen then middleware writes to this file. Standard
output is used otherwise.

=head2 --traffic-log-body-eol

Sets the line separator for message's body for log generated by
L<Plack::Middleware::TrafficLog> middleware.

=head2 --umask

Changes file mode creation mask. The L<perlfunc/umask> is an octal number
representing disabled permissions bits for newly created files. It is usually
C<022> when a group shouldn't have permission to write or C<002> when a group
should have permission to write. (default: none)

=head2 --user

Changes the user id or user name that the server process should switch to
after binding to the port. The pid file, error log or unix socket also are
created before changing privileges. This option is usually used if the main
process is started with root privileges because binding to the low-numbered
(E<lt>1024) port. (default: none)

=head1 ENVIRONMENT

=head2 PUREPROXY_SERVER

Changes the default PSGI server. This is L<Thrall> if Perl supports threads
and L<Starlight> otherwise.
