Abstract: A method and apparatus delays users from accessing a service via the world wide web in an orderly manner without maintaining a queue. When a user requests the service, if the service is busy, a web server does not allow access to the service: instead it configures the user's web browser via a script or applet to periodically retry requesting the service. A timestamp designating a time the user requested the service or other similar time is provided to the user and a count of timestamps issued in different periods are maintained by the web server. The web server periodically determines a cutoff timestamp corresponding to an available capacity of the apparatus using the count of timestamps it maintains. When the user retries requesting the service, the browser provides to the web server the timestamp it received from the server. If the timestamp provided is less than or equal to the cutoff timestamp, the user is allowed access to the service, otherwise, the users browser is instructed to retry at a specified interval.

Abstract translation: 一种方法和装置延迟用户以有序的方式经由万维网访问服务而不维护队列。 当用户请求服务时，如果服务正忙，则Web服务器不允许访问服务：而是通过脚本或小应用程序配置用户的Web浏览器，以定期重试请求服务。 指定用户请求服务的时间或其他类似时间的时间戳被提供给用户，并且由web服务器维护在不同时段中发布的时间戳的计数。 web服务器使用其维护的时间戳的计数周期性地确定对应于设备的可用容量的截止时间戳。 当用户重试请求服务时，浏览器向Web服务器提供从服务器接收的时间戳。 如果提供的时间戳小于或等于截止时间戳，则允许用户访问该服务，否则指示用户浏览器以指定的间隔重试。
