I have spent 8+hours scouring the web, reviewing the Apache Httpd Cookbook, the Definitive Reference, and the 2.2 documentation for mod_headers, mod_proxy and core.
CONFIGURATION:
Apache Version:
Server version: Apache/2.2.15 (Unix)
Server built: Jul 18 2016 15:24:00
SSL offloading happens before the requests gets to Apache, which proxies http traffic to Apache on port 80.
The Apache VirtualHost config in question does not have a ServerName or ServerAlias configured, and is configured to listen on port 80.
SITUATION
I have a Rewrite rule issuing a 301 redirect which uses flags [NC,R=301,L] - which redirects to the correct hostname, but using http as the protocol.
I have a mod_headers rule to try to deal with this: Header always edit Location ^http://(.*) https://$1
This rule is getting completely ignored.
If I add a wholly new Header like: Header always add SillyHeader SillyHeaderValue
the header DOES get added.
Does anyone know why the "Header always edit" rule is getting ignored?
Thank you,
