1. A method in a first communication network node in a communication network for enabling optimised downloading of HyperText Transfer Protocol (HTTP) transferred data to a client, the first communication network node being associated to the client by a first Transmission Control Protocol (TCP) connection, and the first communication network node being further associated to a second communication network node by a second TCP connection, the method comprising:

  • receiving, by the first communication network node, a request from the client, requesting for the HTTP transferred data from the second communication network node,initiating an interaction between the first communication network node and the client by sending to the client a first response in response to the request and sending one or more intermediate responses,determining an available bit-rate for the requested HTTP transferred data at least partly based on the interaction between the first communication network node and the client,forwarding, by the first communication network node, the request to the second communication network node, and forwarding, by the first communication network node, a subsequent response to the client, received from the second communication network node in response to the forwarded request, andforwarding to the client, by the first communication network node, the HTTP transferred data at the available bit-rate, after being received from the second communication network node,wherein the first response, comprising a part of the subsequent response, is sent to the client before remaining parts of the subsequent response are forwarded to the client, andwherein the interaction between the client and the first communication network node to determine the available bit-rate is performed until the HTTP transferred data is made available by the second communication network node.
