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] AUTHOR

Plack::Middleware::StackTrace(3pm)			User Contributed Perl Documentation			Plack::Middleware::StackTrace(3pm)

Plack::Middleware::StackTrace - Displays stack trace when your app dies SYNOPSIS
enable "StackTrace"; DESCRIPTION
This middleware catches exceptions (run-time errors) happening in your application and displays nice stack trace screen. The stack trace is also stored in the environment as a plaintext and HTML under the key "plack.stacktrace.text" and "plack.stacktrace.html" respectively, so that middleware futher up the stack can reference it. This middleware is enabled by default when you run plackup in the default development mode. You're recommended to use this middleware during the development and use Plack::Middleware::HTTPExceptions in the deployment mode as a replacement, so that all the exceptions thrown from your application still get caught and rendered as a 500 error response, rather than crashing the web server. Catching errors in streaming response is not supported. CONFIGURATION
force enable "StackTrace", force => 1; Force display the stack trace when an error occurs within your application and the response code from your application is 500. Defaults to off. The use case of this option is that when your framework catches all the exceptions in the main handler and returns all failures in your code as a normal 500 PSGI error response. In such cases, this middleware would never have a chance to display errors because it can't tell if it's an application error or just random "eval" in your code. This option enforces the middleware to display stack trace even if it's not the direct error thrown by the application. no_print_errors enable "StackTrace", no_print_errors => 1; Skips printing the text stacktrace to console ("psgi.errors"). Defaults to 0, which means the text version of the stack trace error is printed to the errors handle, which usually is a standard error. AUTHOR
