Hi,
we have Bandwidth Gain mode enabled and also included the following line in the local policy:
<Cache>
delete_on_abandonment(yes)
However, when I start a large download (eg releases.ubuntu.com/zesty/ubuntu-17.04-desktop-i386.iso), then cancel this download in the browser again, and go to "Statistics > Sessions > Active Sessions", I can still see the connection and the server bytes are increasing for multiple minutes. Even an ICAP scan is performed in the end.
How can we force the proxy to immediately abandon the connection when it is canceled by the client? Are we misunderstanding delete_on_abandonment(yes)?
Can you reproduce this behaviour on your appliance? We are running SGOS 6.6.5.6.
