Usually, the request will cause the server to send the client another web page, which will in turn contain other links, resulting in an ongoing series of requests from the client interweaved with web pages sent in reply by the server(s). The term “link” is used herein to include both links and forms, along with any other element of a web page that has an associated url, and which a user can click on to send the request in the url to the server mentioned therein. FIG. 3 is a flow chart illustrating the use of continuations to simulate subroutine calls in a program that interacts with the user through successive Web pages
