Case No. IP-2017-000169

28.The PCT Application explains that in the past proxies have been used to enforce a policy for access to websites. However, placing a proxy between the requesting computer and the requested content can create a bottleneck, in that allowed requests may not be fulfilled quickly enough to meet demand. The PCT Application goes on to say that administering proxies can be onerous, particularly in large organisations. 29.The invention claimed provides a means of filtering requests for access to websites without the need of a proxy.
