>Is this a 'curl' question, a 'How do you write CGI?' question or a >general question about how HTTP works? Hi Jonathan, This was just a general question on why I'm not seeing what I expected. I'm using CentOS 7.3, I have written CGI for years (not using user & pass), I've used http for years - I was just hoping someone might be able to shed some light on why I'm not seeing the REMOTE_USER. I did several searches and did not find any resolution. Thanks for any pointers. Jerry
