Authorizer application in Perl (SimpleAuth.pl)

#!/usr/bin/perl

use FCGI;

while (FCGI::accept >= 0) {
		if( $ENV{'HTTP_AUTHORIZATION'} ) { 
        # This value can be further decoded to get the actual 
			# username and password and then
        # perform some kind of user validation. This program only 
        # checks for the presence of
        # of this environment param and is not really bothered about its value

        print( "Status: 200\r\n" );
        print( "\r\n" );

    } else {
       
        print( "Status: 401\r\n" );
        print( "WWW-Authenticate: basic realm=\"foo\"\r\n" );
        print( "\r\n" );  

   }

}

Example obj.conf settings for the above example:

<Object name="responder.fcgi">
		AuthTrans fn="auth-fastcgi" app-path="/fastcgi/apps/auth/SimpleAuth.pl" 
		bind-path="localhost:3432"
		Service fn="responder-fastcgi" app-path="/foo/fastcgi-enabled-php-installation/bin/php" 
		bind-path="localhost:3433" app-env="PHP_FCGI_CHILDREN=8" min-procs=1
</Object>

On first request to http://localhost/fcgi/php/ListDir.php, the authentication dialogue box is displayed by the browser. After the user enters the username and password, the contents of "/tmp" directory gets listed.
