NAME

       Plack::Middleware::ErrorDocument - Set Error Document based on HTTP status code

SYNOPSIS

	 # in app.psgi
	 use Plack::Builder;

	 builder {
	     enable "Plack::Middleware::ErrorDocument",
		 500 => '/uri/errors/500.html', 404 => '/uri/errors/404.html',
		 subrequest => 1;
	     $app;
	 };

DESCRIPTION

       Plack::Middleware::ErrorDocument allows you to customize error screen by setting paths (file system path or URI path) of error pages per
       status code.

CONFIGURATIONS

       subrequest
	   A boolean flag to serve error pages using a new GET sub request.  Defaults to false, which means it serves error pages using file
	   system path.

	     builder {
		 enable "Plack::Middleware::ErrorDocument",
		     502 => '/home/www/htdocs/errors/maint.html';
		 enable "Plack::Middleware::ErrorDocument",
		     404 => '/static/404.html', 403 => '/static/403.html', subrequest => 1;
		 $app;
	     };

	   This configuration serves 502 error pages from file system directly assuming that's when you probably maintain database etc. but serves
	   404 and 403 pages using a sub request so your application can do some logic there like logging or doing suggestions.

	   When using a subrequest, the subrequest should return a regular '200' response.

NAME

       Plack::Middleware::Static - serve static files with Plack

SYNOPSIS

	 use Plack::Builder;

	 builder {
	     enable "Plack::Middleware::Static",
		 path => qr{^/(images|js|css)/}, root => './htdocs/';
	     $app;
	 };

DESCRIPTION

       Enable this middleware to allow your Plack-based application to serve static files.

       If the given request matches with the pattern defined in "path", this middleware will try to locate the file in "root". If the file exists
       it will be served but otherwise 404 response will be returned. See "pass_through" option below to change this behavior.

       If the requested document is not within the "root" (i.e. directory traversal) or the file is there but not readable, a 403 Forbidden
       response will be returned.

       The content type returned will be determined from the file extension based on Plack::MIME.

CONFIGURATIONS

       path, root
	     enable "Plack::Middleware::Static",
		 path => qr{^/static/}, root => 'htdocs/';

	   "path" specifies the URL pattern (regular expression) or a callback to match with requests to serve static files for. "root" specifies
	   the root directory to serve those static files from. The default value of "root" is the current directory.

	   This examples configuration serves "/static/foo.jpg" from "htdocs/static/foo.jpg". Note that the matched "/static/" portion is still
	   appears in the local mapped path. If you don't like it, use a callback instead to munge $_:

	     enable "Plack::Middleware::Static",
		 path => sub { s!^/static/!! }, root => 'static-files/';

	   This configuration would serve "/static/foo.png" from "static-files/foo.png" (not "static-files/static/foo.png"). The callback
	   specified in "path" option matches against $_ and then updates the value since it does s///, and returns the number of matches, so it
	   will pass through when "/static/" doesn't match.

	   If you want to map multiple static directories from different root, simply add "this", middleware multiple times with different
	   configuration options.

       pass_through
	   By turning on this option, this middleware will pass the request back to the application for further processing, if the incoming
	   request path matches with the "path" but the requested file is not found on the file system.
