A method of three-level hosting infrastructure provides a server computer accessible to users through hosts. The hosting infrastructure includes hosting resources used by the server computer for the benefit of at least a first host. The first host then uses the hosting resources of the server computer and also hosts one or more other hosts, who may use the hosting resources through the first host. The method enables one host to be included into another host. The method enables received content at the hosting infrastructure to be hosted by two or more hosts.
