Abstract
A method and apparatus are disclosed for providing persistent storage of Web resources. Uniform Resource Locators (“URLs”) that identify Web resources are augmented to include a time stamp. A web browser and a web server are disclosed that accommodate a time stamp parameter and allow a user to refer to any Web address with a precise target date. The persistent Web servers (i) receive URLs containing a time stamp, (ii) extract the time stamp, (iii) retrieve the correct Web page from the archive, and (iv) return the requested page to the client. The persistent Web servers include a persistent archive for storing all of the versions of Web resources that will be persistently available to Web users. A persistent domain name server (PDNS) allows a user to refer to historical Web resources. The persistent domain name server (PDNS) utilizes the dated URL to determine where the historical information of a given company is located following a domain name change for the requested time period and translates the request to a new machine containing the historical information of the company.
