I've searched the perlmonks archives and have seen references which use mod_perl to handle situations such as this. However, mod_perl is not available to me at the moment.

You may be out of luck. mod_perl is integrated with Apache, and can do things that CGI scripts cannot.

I'm really trying to avoid a double login process.

The common way to do this is to forgo web server authentication (i.e., .htaccess control) entirely, relying instead on application-level login. Can you say more about why you need both?
