`rewrite` options should apply to all responses

Created by: tillsc

According to the documentation the hostRewrite and autoRewrite options only apply to 3xx responses. But the Location-Header is allowed in more than only the 3xx responses (e.g. in 201 Created).

I don't understand why it is necessary to limit this functionality to specific response codes. Why couldn't just every Location header be analyzed and replaced if there is one present in the response?
