System and method for enabling a web site robot trap

摘要

The invention allows a system to prevent robots from browsing a Web site beyond a welcome page. When an initial request from an undefined originator is received Web site responds to it with a welcome page including at least one trap. Then, on receiving further requests from the undefined originator Web site can check whether a trap is used or not. If not used the undefined originator is assumed to be a human being and is authorized to go on. If a trap is however used the undefined originator is assumed to be a robot in which case site access is further denied. The invention prevents Web site contents from being investigated by robots while not requiring users to have to log on.
