3.1.6.2 Network Receive IO Timer Event

The NetworkReceiveIO Timer Event fires when an entity body fragment is not received on the GET session within the specified amount of time. If the NetworkReceiveIO event triggers, the client SHOULD close the LongLived connection, but can retry immediately as specified in section 3.1.4.1. This timer event will not occur on well behaved connections, as the encapsulated protocol SHOULD have implemented the KeepAlive timer as specified in section 3.1.2.3, which SHOULD have used a timer value smaller than the NetworkReceiveIO timer value.
