mod_perl Basic Auth

mod_perl Recipe

Challenge

http://www.example.com/my/ should be password protected through a Custom Basic Authorization
Under /my/x/ you want to run executable scripts which are protected through the Basic Auth as well
You want putting static HTML pages under /my/, e.g. /my/hello.html which should be accessible through a Web Browser
You'd like to run scripts in mod_perl fashion within this Basic Auth along the possibilty to configure a CGI directory

Recipe

Edit your httpd.conf (or ssl.conf)

<VirtualHost>
...
	# --- CGI replacement:
	Alias /my/x/  /usr/local/apache2/ssl.pgate.net/my/x/
	<Location /my/x/>
		SetHandler perl-script
		PerlHandler ModPerl::Registry
		PerlSendHeader On
		Options +ExecCGI
	</Location>
	<Location /my/>
		AuthType Basic
		AuthName "The GATE"
		Require valid-user

		# mod_perl Basic Auth:
		PerlAuthenHandler Custom::Login
		ErrorDocument 401 /nok.htm
	</Location>
...
</VirtualHost>
