Before Apple's browser was released as Safari, it was known as "Freedom" — and it masqueraded as both Internet Explorer and a Mozilla browser. Don Melton, who started the original Safari project, describes the secrecy under which his team operated, both physically on Apple's campus and virtually as he devised ways to hide Safari's user agent information out of fear it would be connected to Apple's block of IP addresses, then to release it a few days before the announcement. "I spent the days before [Safari's] debut nervous and losing sleep," he writes, "as I combed the Internet for server logs."
