Subject: [MMUSIC] RTSP REDIRECT (1) , when can it be
received ??

Hi,

I have problem understanding *when* a user agent can
receive a REDIRECT request.

When reading RFC 2326, I understood
receipt/transmission of a REDIRECT request could happen
at virtually anytime. As such, the following scenario
could happen:

C -> S: DESCRIBE rtsp://server.com/movies/BeautifulMind.mp4
CSeq: 1400
Accept: application/sdp

S -> C: REDIRECT rtsp://server.com/movies/BeautifulMind.mp4
CSeq: 1401
Location: rtsp://server.com/mpaa/pg13/BeautifulMind.mp4

S -> C: RTSP/1.0 404 Not Found
CSeq: 1400
Connection: Close

However one can also notify redirection in such a
context by using a 3xx
response, right ?
C -> S: DESCRIBE rtsp://server.com/movies/BeautifulMind.mp4
CSeq: 1400
Accept: application/sdp

S -> C: RTSP/1.0 301 Moved
CSeq: 1400
Location: rtsp://server.com/mpaa/pg13/BeautifulMind.mp4
Connection: Close

However when reading the RTSP state machine spec
(version 0.5) contributed by Mr Westerlund, it seems
like a REDIRECT can only happen (or at least
should be used) when a presentation is being played or
is paused (at least all streams are SETUP). Therefore
using the state machine REDIRECT semantics, scenarii
like the first one exposed above are erroneous.

So should REDIRECT be sent/received when an RTSP
session is being played/paused only, or can it be
sent/received any time ??

Thanks for your time and response,

Olivier
