Support of Byte-Range Requests

1 Initial Problem

The download of mediacast elements (e.g., mp4, m4a, mp3, etc.) is not possible on iOS devices by now.
This is because for the display of the individual media files in the browser (previous to the download) Apple expects from pages on a the web server that the support of so-called "byte-range" requests. These are necessary for the respective media player to fast-forward to a certain point of time in the video or audio stream.
ILIAS seems to lead the download request via PHP and, in that course, not to support the corresponding "byte range" request.
As iOS devices are widely spread, we consider this seems a serious problem which, however, should be easy to fix. Information about that topic can be found here, e.g.:
