the "Server: field, which can be used to identify some special-case servers that are not 100% standards-compliant.

We use this to identify Windows Media Server, which has a value "WMServer/v.e.r.sion", where version is a sequence of digits (e.g. 9.0.0.3372). Helix/Real servers use something like "Helix [..] Server Version v.e.r.sion (platform) (RealServer compatible)" or "RealServer Version v.e.r.sion (platform)", where platform is the output of $uname -msr | sed 's/ /-/g'.

the "Session:" field.

This value is initially set by the server and should be re-transmitted by the client in every RTSP command.

Definition at line 139 of file rtsp.h.

The "timeout" comes as part of the server response to the "SETUP" command, in the "Session: <xyz>[;timeout=<value>]" line.

It is the time, in seconds, that the server will go without traffic over the RTSP/TCP connection before it closes the connection. To prevent this, sent dummy requests (e.g. OPTIONS) with intervals smaller than this value.
