(RFC 2326’s only mention of this is in the table in section 12, where it notes that the “Session:” header is valid for “all but SETUP, OPTIONS” - which is somewhat dubious, because the “Session:” header *is* used in (all but the first) “SETUP” commands in a multi-track stream.) If a server doesn’t expect to see a “Session:” header in the “OPTIONS” command, then it’ll probably just ignore it, rather than returning an error. On the other hand, I have heard of servers that complain if the “Session:” header is *not* present in the “OPTIONS” command (once a session has been established). And I’ve heard of servers that handle “OPTIONS”, but not “GET_PARAMETER”, even sometimes when they return “GET_PARAMETER” as one of their supported commands in response to an initial “OPTIONS” request!<div class=""><br class=""></div><div class="">The bottom line is that there are a lot of fucked up servers out there, but sending “OPTIONS” (with a “Session:” header if appropriate) seems to work more often than either sending “OPTIONS” without “Session:” header, or “GET_PARAMETER”. This is what the "LIVE555 Proxy Server” does, for example.</div><div class=""><br class=""></div><div class="">But, to be safe, you might wish to send “OPTIONS” (with the “Session:” header, where appropriate) only for Julian Scheel’s new “satip” access method, but continue to use “GET_PARAMETER” for regular “rtsp” access.
