OK, I've upgraded to this version.

I've now confirmed this to be the case, thanks!

What would be a good way to modify the proxy server such that:
1. The connection to a proxied server is torn down and setup again if
the server is not sending any data
2. The connection to a proxied server is torn down and setup again if
there is a mismatch between "Session" expected by the proxy server and
what is sent in responses from the server

> So this ‘back-end’ server happens to also be using our code - but a very old version (that is therefore known to be buggy).  Is this back-end server something that you control?
> If so, you should upgrade it to use the latest version of our software.
> Note that if the server is a product (e.g., part of a network camera that you own) then - under the terms of the LGPL - the manufacturer is obligated to let you update the LIVE555 library code that it uses.
> If you are unable to upgrade the LIVE555 library on this ‘back-end’ server, then please let me know, and I’ll try to get in touch with the manufacturer, reminding them of their legal obligations.
It's a Xiaomi Yi Home camera.
Unfortunately, there doesn't seem to be sourcecode available for the
RTSP server running on the camera.
