-### (Optional): access by a different virtual hostname
-
-When hostname-based authentication is in use, it's necessary to access
-the Service Proxy as the correctly named virtual host. This can be
-done by setting the `service_proxy_auth` configuration item to a
-URL containing that hostname, such as
-`//yourname.sp-mkws.indexdata.com/service-proxy/?command=auth&action=perconfig`
-
-> TODO It should be possible to change just the hostname without
-> needing to repeat the rest of the URL (protocol, path, query): see
-> **MKWS-252**.
-
-> TODO When changing the SP authentication URL, the Pazpar2 URL should
-> in general change along with it: see **MKWS-253**.
