[users@httpd] password protected site

[Jay]

Hello all, don't know if this is possible but I thought I'd ask anyways.   I have an internal website that I've used the allow,deny feature and narrowed it down to only allow our main office and our remote offices to view this site.   I have some users though, that when they are out on the feild, from time to time need access to the internal site. It there a way to let the thise people view it by some sort of authenication?   Hope this makes sense,   thanks, Jay
