Hi everyone,

I would like to deploy RT 4.2.9 on apache2 with FastCGI mod in localhost,
What should I put as values in the RT_SiteConfig.pm?

Set( $WebDomain, '?????' );
Set( $WebPath, '??????' );
Set( $WebPort, '??????' );

and what value should I put in the apache2 conf file ?


    <VirtualHost ????? >
    </VirtualHost>

Thanks in advance,
