There is provided a method for categorising a downloading of a resource to a user device from a resource server in a data network. Data of one or more Layer 7 protocol requests from the client device is received at an intermediate server in the data network. Each of the one or more Layer 7 protocol requests is a request for a different portion of, or the whole of, the resource to be downloaded to the client device. The intermediate server forwards the data of each of the one or more Layer 7 protocol requests to the resource server. The intermediate server receives data of one or more Layer 7 protocol responses from the resource server, each Layer 7 protocol response corresponding to a respective one of the Layer 7 protocol requests and determines a size of, or an estimate of the size of, the one or more Layer 7 protocol responses. The intermediate server categorises the downloading of the resource to the client device as being one of one or more pre-defined download categories, based on a count of the one or more Layer 7 protocol responses and the determined sizes or estimated sizes of the one or more Layer 7 protocol responses. |
