Goal

The goal of this note is to show the directives needed to trace cache headers in oracle HTTP server $ORACLE_HOME/Apache/Apache/logs/access_log file.

The usage of this feature is to help diagnose issues, for example it helped to diagnose an issue related to SSO. In that case the user was only required to sso login once. Next requests for the secured page from different workstations resulted in a response without the customer needing to login. Trace of oracle http server headers showed the responses had correct cache headers (  not to cache them), but webcache cached the pages anyway.
