Mime Troubles? File not loading using URL from HANA server.

I am trying to run the Visual Enterprise Viewer on a HANA Server.

I have established the following in my .xsacess file.

{

"exposed": true,

"authentication": [{ "method": "LogonTicket" }, { "method": "Basic"}],

"mime_mapping" : [{ "extension":"rh", "mimetype":"application/rh" },

      { "extension":"vds", "mimetype":"application/vds" }]

}

I can open the the .rh file perfectly from the Viewer itself if I open the file itself.

BUT - if I use a URL (which works from most servers) the file cannot be found.

My URL looks like this

http://HANA:8080/workshop/ve/mini/file.rh

I believe that the "mime_mapping " is not having an impact on the web server on HANA. Or perhaps it has to be restarted?
