Redirection headers and m4a file

Hello,

first – hat’s off to you and your work.

I’ve encountered a strange behaviour and I’m not sure if
it’s related to my hosting or the way, browser (Firefox)
handles redirections, or maybe it’s WP/MediaElement thing.

In normal use scenario, when I’m trying to play m4a file
(without ssp_use_raw_audio_file_url function engaged),
the player does nothing but console returns error regarding
wrong Content type headers (text/plain) being declared.

Redirect doesn’t work from player level, it returns an error
instantly. It works like a charm when called from browser’s
url bar, using simple get or curl.

I assume, that player tries to load redirect as an audio file
and something doesn’t work quite well.

I tried several tricks with php and htaccess rules but I’m
stuck and forced to use raw_audio_file_url for now.

Is this a feature or a bug? ?? Okay, is there any way
to implement custom Content-type headers for
redirection or maybe that’s a flaw that affects only
some users and relates to their hosting configuration?

Regards,
Tomek
