I have some trouble with access to password protected content.
My webserver is set to ask for a user and password using .htaccess and .htpasswd. This works absolutely fine, when I access my webserver through http://localhost/.
But when other people access through an external IP, they have to re-authenticate every time they click a new link, or access a different file. This is disastrous because I'm encorporating this into a program which can't handle being asked for user/pw every 5 seconds! (apache)
AuthName "Secure Area"
