Clients making requests from Icecast 2.3.1 server with HTTP Range header using units "bytes" with any casing other then all lowercase fail request with:

HTTP/1.0 416 Request Range Not Satisfiable

It is expected that the HTTP Range header should be case insensitive on "bytes"

W3C rfc2616 HTTP 1.1 sec 2.1 (http://www.w3.org/Protocols/rfc2616/rfc2616-sec2.html#sec2.1) states about BNF literals "Unless stated otherwise, the text is case-insensitive."

Section 3.12 (http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.12) which defines the Range units defines "bytes", but does not specify case sensitivity.

Here is an example localhost request/response against an icecast 2.3.1 server with Range units as "Bytes":

REQUEST: **************\n
GET /TheBeginning.mp3 HTTP/1.1\r\n
Range: Bytes=0-\r\n
Host: localhost\r\n
Accept: */*\r\n
\r\n
RESPONSE: **************\n
HTTP/1.0 416 Request Range Not Satisfiable\r\n
\r\n
