Apache configuration debugging / Splunk SSO by apache reverse proxy with CORS

[juhanishen <juhanishen@xxxxxxx>]

Hi: Experts:

I ha\ve snipped apache configuration as follows /1/. 

When I hard code Remote_User as supervisor, Splunk SSO functions. Then I suspect ssouser does not get the value. How could I print or log the ssouser when RewriteCond is invoked so that I know in the %{HTTP_COOKIE} I have ssouser and its value is given/assigned?
