Dynamic integration of web sites

Apparatus for serving a Web page component based on computer-readable code provided at a first Web site on a network, which code, when read by a client computer, causes the computer to display at least a first Web page, the code including one or more links to resources at the first Web site, the apparatus comprising:

• a network interface, for communicating with the network;
• and
• a component server, which is separate from the first Web site and is adapted to receive an indication of at least a portion of the code at the first Web site that has been selected for inclusion in the Web page component, the selected portion comprising at least one of the links,
• wherein the component server is adapted, responsively to an invocation by the client computer of a pointer to the component server in a second Web site, to read the selected code from the first Web site and to modify the at least one of the links so as to create a modified link, which permits the client computer to use at least one of the resources while accessing the Web page component via the component server, and to convey the selected code, including the modified link, to the client computer so as to cause the client computer to display the Web page component.
