Dynamic integration of web sites

A component server, comprising computer apparatus that is adapted to receive an identification of computer-readable service code at a service site, which code is written in a mark-up language, such that when the code is read by a browser program on a client computer via a network, the code causes the computer to display at least one service page containing service information,

• wherein at least a portion of the service code is selected for inclusion in a service component containing at least a portion of the service information that corresponds to the selected code, and
• wherein a pointer is generated indicating a location of the server at which the service component is accessible, for inclusion of the pointer in host code accessible to the client computer from a host site, which is separate from the service site and is accessible via the network, the host code, when read by the client computer, causing the computer to display a host page containing host information,
• which apparatus is further adapted to receive via the network an invocation of the pointer by the client computer when the client computer accesses the host page, and to convey to the client computer over the network a script command for execution by the browser program on the client computer, the script command having at least a part of the selected service code as an argument, such that responsive to the script command, the client computer displays the service component on the host page.

A computer software product, comprising a computer-readable medium in which program instructions are stored, which instructions, when read by a computer server, cause the server to receive an identification of computer-readable service code at a service site, which code is written in a mark-up language, such that when the code is read by a browser program on a client computer via a network, the code causes the computer to display at least one service page containing service information,

• wherein at least a portion of the service code is selected for inclusion in a service component containing at least a portion of the service information that corresponds to the selected code, and
• wherein a pointer is generated indicating a location of the server at which the service component is accessible, for inclusion of the pointer in host code accessible to the client computer at a host site, which is separate from the service site and is accessible via the network, the host code, when read by the client computer, causing the client computer to display a host page containing host information, and
• wherein the instructions further cause the server to receive an invocation of the pointer by the client computer when the client computer accesses the host page, and to convey to the client computer a script command for execution by the browser program on the client computer, the script command having at least a part of the selected service code as an argument, such that responsive to the script command, the client computer displays the service component on the host page.
