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]

NAME

       Plack::Middleware::AccessLog - Logs requests like Apache's log format

SYNOPSIS

	 # in app.psgi
	 use Plack::Builder;

	 builder {
	     enable "Plack::Middleware::AccessLog", format => "combined";
	     $app;
	 };

DESCRIPTION

       Plack::Middleware::AccessLog forwards the request to the given app and logs request and response details to the logger callback. The format
       can be specified using Apache-like format strings (or "combined" or "common" for the default formats). If none is specified "combined" is
       used.

       This middleware uses calculable content-length by checking body type, and can not log the time taken to serve requests. It also logs the
       request before the response is actually sent to the client. Use Plack::Middleware::AccessLog::Timed if you want to log details after the
       response is transmitted (more like a real web server) to the client.

       This middleware is enabled by default when you run plackup as a default "development" environment.

CONFIGURATION

       format
	     enable "Plack::Middleware::AccessLog",
		 format => '%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-agent}i"';

	   Takes a format string (or a preset template "combined" or "custom") to specify the log format. This middleware implements a subset of
	   Apache's LogFormat templates <http://httpd.apache.org/docs/2.0/mod/mod_log_config.html>:

	      %%    a percent sign
	      %h    REMOTE_ADDR from the PSGI environment, or -
	      %l    remote logname not implemented (currently always -)
	      %u    REMOTE_USER from the PSGI environment, or -
	      %t    [local timestamp, in default format]
	      %r    REQUEST_METHOD, REQUEST_URI and SERVER_PROTOCOL from the PSGI environment
	      %s    the HTTP status code of the response
	      %b    content length
	      %T    custom field for handling times in subclasses
	      %D    custom field for handling sub-second times in subclasses
	      %v    SERVER_NAME from the PSGI environment, or -
	      %V    HTTP_HOST or SERVER_NAME from the PSGI environment, or -

	   Some of these format fields are only supported by middleware that subclasses "AccessLog".

	   In addition, custom values can be referenced, using "%{name}", with one of the mandatory modifier flags "i", "o" or "t":

	      %{variable-name}i    HTTP_VARIABLE_NAME value from the PSGI environment
	      %{header-name}o	   header-name header
	      %{time-format]t	   localtime in the specified strftime format

       logger
	     my $logger = Log::Dispatch->new(...);
	     enable "Plack::Middleware::AccessLog",
		 logger => sub { $logger->log(level => 'debug', message => @_) };

	   Sets a callback to print log message to. It prints to "psgi.errors" output stream by default.
