allow a file to be viewed as opposed to download. This is particularly needed when a video file is stored
        in the fileservice and user wants to be able to use a view the video as opposed to having to download it
        first. It passes the serving of the file to nginx/apache which will return all the proper headers allowing,
        say, html5's video viewer's 'seek' indicator/knob to work. Otherwise the video is only played sequentially

        Note that nginx/apache need to be configured accordingly. nginx for example:
        location /var/lib/geoserver_data/file-service-store/ {
           # forces requests to be authorized
           internal;
           alias   /var/lib/geoserver_data/file-service-store/;
        }

        for apache, need to install xsendfile module, enable it, set the path and then
        XSendFile on
        XSendFilePath /var/lib/geoserver_data/file-service-store

        example use:
        /fileservice/view/med.mp4
        or
        /fileservice/med.mp4/view

        Note that media players tend to require the route to end with the filename like /fileservice/view/med.mp4
