Hello Ross
Many thanks!!!
I've been testing the new release and it fixes the bug that I reported
last week. When a BYE is received from the backend, the proxy doesn't crash.
But, once the connection with the frontend client is closed, if you try
to connect again to the stream source, a new error appears.
You can see below a complete log of a test connecting against a Mpeg4
stream source (through TCP):
