Abstract: Methods and apparatus at servicing-linked applications in a client-server environment are disclosed. A client 20 is in communication with a server 30, and both are running a main application (in one form a goods and services ordering application). An associated application (for example, On-Line Help) is supported by a second server 30′. When OLH is invoiced on the client 20, a unique identifier is passed to the main application server 30, which locates a corresponding URL string and passes the string to a browser 130 on the client 20. The browser 130 passes the URL to the OHL server 30′ where the respective OLH document is retrieved from a datastore 40, and returned to the client 20 for display on the screen 100.
