Transports need to send "Keep Alives"

[ielbury]

In order to better support traversing network equipment that perform an kind of proxy function such as load balancers, UTM (Unified Thread Managment) appliances/software, proxy servers etc, a "keep alive" is required to keep the connection open.

The current time-out mechanism makes the streaming protocols no different then long polling given the dynamics and payload.

Until this issue is resolved, users will likely be better off with a long polling solution.

You can make the timeout infinite if you wanted to simulate the old behavior. We'll look at keep alive in the next release.

Fixed in 832383d.

You can set the KeepAlive property on the ConfigurationManager and SignalR will send an empty frame of data (based on the transport) on the specified interval to keep the connection alive.
