Ian Boston commented on SLING-6046:
-----------------------------------
Some questions:
Is it just video/mp4 that matter or all large files ?
Does IE use the response from other resources to determine if it can send a
range header on the first request for the large file ?
Patch looks fine, I am wondering if serving these files via the JVM is the
right thing to do and if it would not be better to have proper X-sendfile
support protected by appropriate AuthZ.
IIRC Sling uses Jetty that will transfer files using http chunked transfer
encoding [1], provided no content-length header is sent in the response and the
output stream is flushed at appropriate moments. If the transfer encoding is
chunked, how does the video play in IE11, I realise the transfer will start
from the beginning and there wont be support for fast forward, but will the
video start playing immediately ?

> Since IE 11 expects "Accept-Ranges" [0] response header to start making
> requests with Range header, so sling lack in streaming of video content for
> IE end users. We can add Accept-Ranges = bytes header to response , either
> selectively only for video/mp4 mimetype ( video tag on IE looks for mp4 ) or
> always.
> Without support of partial content response (206) for IE users, all large
> video files are being downloaded in single chunk and user need to wait for
> long to see video content playing.
