[plt-scheme] web server directories

A while ago, Jens Axel Søgaard wrote that the PLT web server could be 
proxied by Apache:

I think I already know the answer to this one, but before I go through 
with setting up the whole deal, I'd like to be sure:  if I'm handling 
user logins through Apache's .htaccess, will the username given to 
Apache be available to the PLT server via extract-user/pass?

Thanks,
