NAME

       Plack::Middleware::Expires - mod_expires for plack

SYNOPSIS

	 use Plack::Builder;

	 builder {
	     enable 'Expires',
	       content_type => qr!^image/!i,
	       expires => 'access plus 3 months';
	     $app;
	 }

DESCRIPTION

       Plack::Middleware::Expires is Apache's mod_expires for Plack.  This middleware controls the setting of Expires HTTP header and the max-age
       directive of the Cache-Control HTTP header in server responses.	Note: Expires works only for successful response and If exists Expires
       HTTP header already, this middleware does not override.

CONFIGURATIONS

       content_type
	     content_type => qr!^image!,
	     content_type => 'text/css',
	     content_type => [ 'text/css', 'application/javascript', qr!^image/! ]

	   Content-Type header to apply Expires

       Expires
	   Same format as the Apache mod_expires

	     expires => 'M3600' # last_modified + 1 hour
	     expires => 'A86400' # access + 1 day
	     expires => 'modification plus 3 years 3 month 3 day'
	     expires => 'access plus 3 days'

NAME

       Plack::Middleware::Conditional - Conditional wrapper for Plack middleware

SYNOPSIS

	 use Plack::Builder;

	 builder {
	     enable_if { $_[0]->{REMOTE_ADDR} eq '127.0.0.1' } 'StackTrace', force => 1;
	     $app;
	 };

	 # or using the OO interface:
	 $app = Plack::Middleware::Conditional->wrap(
	     $app,
	     condition	=> sub { $_[0]->{REMOTE_ADDR} eq '127.0.0.1' },
	     builder => sub { Plack::Middleware::StackTrace->wrap($_[0], force => 1) },
	 );

DESCRIPTION

       Plack::Middleware::Conditional is a piece of meta-middleware, to run a specific middleware component under runtime conditions. The goal of
       this middleware is to avoid baking runtime configuration options in individual middleware components, and rather share them as another
       middleware component.

EXAMPLES

       Note that some of the middleware component names are just made up for the explanation and might not exist.

	 # Minify JavaScript if the browser is Firefox
	 enable_if { $_[0]->{HTTP_USER_AGENT} =~ /Firefox/ } 'JavaScriptMinifier';

	 # Enable Stacktrace when being accessed from the local network
	 enable_if { $_[0]->{REMOTE_ADDR} =~ /^10.0.1.*/ } 'StackTrace';

	 # Work with other conditional setter middleware:
	 # Transcode Jpeg on the fly for mobile clients
	 builder {
	     enable 'MobileDetector';
	     enable_if { $_[0]->{'plack.mobile_detected'} }
	       'TranscodeJpeg', max_size => 30_000;
	     $app;
	 };

       Note that in the last example MobileDetector should come first because the conditional check runs in pre-run conditions, which is from
       outer to inner: that is, from the top to the bottom in the Builder DSL code.
