[Archivesspace_Users_Group] Serving ArchivesSpace with prefix and proxy

I think the main problem here was that the instructions for running ArchivesSpace under a prefix were a little half-baked - I’ve reworked things so that in the next release the same set of configuration parameters referenced in the instructions for configuring HTTPS can also be used to configure prefixing by way of the Apache Proxy and ProxyPass directives. You can see the documentation here - note that this does not apply to the current release:
