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.

NAME

       Plack::Middleware::Auth::Basic - Simple basic authentication middleware

SYNOPSIS

	 use Plack::Builder;
	 my $app = sub { ... };

	 builder {
	     enable "Auth::Basic", authenticator => &authen_cb;
	     $app;
	 };

	 sub authen_cb {
	     my($username, $password) = @_;
	     return $username eq 'admin' && $password eq 's3cr3t';
	 }

DESCRIPTION

       Plack::Middleware::Auth::Basic is a basic authentication handler for Plack.

CONFIGURATION

       authenticator
	   A callback function that takes username and password supplied and returns whether the authentication succeeds. Required.

	   Authenticator can also be an object that responds to "authenticate" method that takes username and password and returns boolean, so
	   backends for Authen::Simple is perfect to use:

	     use Authen::Simple::LDAP;
	     enable "Auth::Basic", authenticator => Authen::Simple::LDAP->new(...);

       realm
	   Realm name to display in the basic authentication dialog. Defaults to restricted area.

LIMITATIONS

       This middleware expects that the application has a full access to the headers sent by clients in PSGI environment. That is normally the
       case with standalone Perl PSGI web servers such as Starman or HTTP::Server::Simple::PSGI.

       However, in a web server configuration where you can't achieve this (i.e. using your application via Apache's mod_cgi), this middleware
       does not work since your application can't know the value of "Authorization:" header.

       If you use Apache as a web server and CGI to run your PSGI application, you can either a) compile Apache with
       "-DSECURITY_HOLE_PASS_AUTHORIZATION" option, or b) use mod_rewrite to pass the Authorization header to the application with the rewrite
       rule like following.

	 RewriteEngine on
	 RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
