So he tried passive resistance by drawing a virtual curtain around his Web site. The trick, called cloaking, made his blog appear seemingly abandoned to her, while his regular postings were available to anyone else with a Web browser.

New tools let people draw a virtual curtain around a Web site to mask sensitive information from outsiders.
Web site operators and corporations are latching on to the cloaking practice as it becomes a growing strategy for playing espionage with rivals.
