In this paper, we propose a new protocol namely Web Recency Maintenance Protocol (WRMP) that employs "push" mechanism to maintain the currency of the World Wide Web (WWW) at Search Engine (SE) site. As of this writing SEs are adopting "pull" technology, by employing search bots to collect the data from WWW. Pull technology can no longer cater to the growing user base and the information explosion on the web. In view of the gigantic structure and dynamic nature of the WWW, it is impractical to maintain the currency using this technology. This practical limitation makes SEs yield stale results. WRMP ensures the real time update by initiating an update agent as and when the server is modified or updated. The availability of high processing speed enables the SE to maintain the currency of the whole WWW in real time. This protocol cuts down the unwarranted roaming of the search bots and takes the real purpose of the web server establishment i.e. reach the public over Internet as the motivating factor. This protocol gives an additional advantage to the SE by enabling it to prioritize the Web sites based on the change frequency. We have given a formal specification for the protocol and an M/M/1 model based analysis.
