A proxy acting as a content gateway manages the download of content data from a server to a client PC. Rather than serving the content data directly to the client, the proxy intercepts the download and instead passes a download management entity (DME) to the client PC. A range of content management services can be applied to the downloaded content data (e.g. the data can be scanned for viruses). The DME, meanwhile, reflects the status of the download to the client PC: it may for example display the percentage downloaded or the fact that the downloaded data is being scanned for viruses. In one particular embodiment, having established that the downloaded data is clear of undesirable content (e.g. viruses, pornographic content etc.), the DME then streams the downloaded data to the client PC.
