Forgot to mention that redirects in a subrequest won't affect its
parent requests. They're separate requests anyway. Try thinking about
it :)

Use either ngx.req.set_uri() or ngx.exec() in rewrite_by_lua. (If you
use content_by_lua, then you can only use ngx.exec for internal


Also, it is a bad idea to enable "share_all_vars" due to potential bad
side-effects that lead to weird issues that are extremely hard to
debug. Just share the NGINX variables you want to share.
