Subject Re: [users@httpd] Apache 2.2 mod_headers question
Date Tue, 07 Feb 2017 13:09:25 GMT
Thank your for your reply.

Yes, I have already traveled down that route and talked with our DevOps
guys.  The system that handles SSL termination is a system they want little
or no configuration on.  They (DevOps) understand that this could be
handled there, but they wont make the change there.

That still leaves me in a position to fix this problem.

Mod_headers should allow me to edit that Header, but in this specific case,
for whatever reason, Mod_headers is not being invoked.
