@joerghoh is there a more generic way to make this happen? Many customers, consultants deploy WKND to non production environments for testing, demo, POC and other types of work. This change would force all of those environments to redirect the live site...

Technically mod_rewrite is not longer required to write the location header with the protocol and hostname. While this is specified since a while (RFC 7231) I haven't found it documented for mod_rewrite on Apache side, so it still uses the "old behavior": It deduces the protocl and hostname part from the other information in the http header.

According to this SO article it should be possible using mod_header, but I haven't got it working yet with my local setup yet:

Header always edit Location "(^http[s]?://)([a-zA-Z0-9\.\-]+)(:\d+)?/" "/"

@joerghoh could we use dispatcher variables for this? I suppose the default would have to work for local dev (empty value) and when its deployed to an AEM CS service, the user would have to make sure to set the value to the appropriate scheme/host. Couldn't find the docs on this quick enough, so figured a quick note back might be faster :)
