Slightly more alarmingly we have had one report (and only one report to date) where the Send button only works intermittently,
A bit of experimentation last night demonstrates that if someone clicks "Send" after a login session has expired then roundcube just sits there with a spinning "sending" icon at the bottom left.
The user doesn't get to see a popup alert to explain what has happened (although on the positive side it doesn't just throw away the message).
I imagine that is what is being reported here. While the KeepAlive stuff seems to be working, I imagine that it is quite common for people to close up their laptop and move to another room before continuing a message.
We are currently using the default:
// Session lifetime in minutes $rcmail_config['session_lifetime'] = 10;
which seemed sensible for permanently on connections.
I guess that I could increase that to an hour, or maybe two hours.
I am curious what other people use for session_lifetime, as this must be a fairly widespread problem for Roundcube deployments.
