I changed the rule line to:
{"/music/[...]", cowboy_static, {dir, "", [
{mimetypes, cow_mimetypes, all}]}},
The client I am using is 'mplayer'. The error message is:
Server returned 400:Bad Request
Failed to parse header.
Failed, exiting.
I also included some tracing in my middleware module to print
out the new path and path_info values it is setting, showing
the result of the rewrite algorithm.
Path <<"/music/Library/Folk/Swiss/Alphorn.ogg">>
Info [<<"/">>,<<"music">>,<<"Library">>,<<"Folk">>,<<"Swiss">>,
<<"Alphorn.ogg">>]
