Re: [frenchface] .htpassword and a chat script [In reply to] Can't Post
this script doesnt ask for a password, so why would you want to integrate that with htpasswd?

If your web server is handling the authentication, see if it is setting $ENV{REMOTE_USER}.

See http://hoohoo.ncsa.uiuc.edu/cgi/env.html for more info on REMOTE_USER.

Thanks for your advice it worked perfectly. Now is there a way I can modify the script to make it automatically refresh? Just the part where the people talk and not the entire page?

Re: [frenchface] .htpassword and a chat script [In reply to] Can't Post
I added the code so that it auto refreshing, when you are typing and it refreshes it is kinda anoying because it takes the curser off the box you are typeing, is there a way to keep the curser in the chat box?
