Remote visitors' username

[Anon]

I want to track remote visitors' username(DISPLAY NAME sent with the e-mail headers)by using Environment Variable, much like we track remote visitors' IP address using $REMOTE ADDR. Please Help

Have you tried $REMOTE_USER??

Mark.

Small note: users only have a username if they logon to your website through HTTP-authentication.

No logon to your website: no username.
