Roy Fielding, co-founder of the Apache HTTP Server project and one of the Do Not Track (DNT) standards authors, wrote a patch for Apache HTTP Server: If the browser that accesses the Web Server is IE10, it ignores its DNT settings. By default, Microsoft IE10 enables DNT, which can better protect user privacy. Microsoft's practices are neither consistent with those of other browser developers nor recognized by online advertisers.
Mozilla believes that DNT should be neither active nor inactive before user settings. Digital Advertising Alliance adopts this stance, indicating that only DNT settings that are disabled by default are accepted. In other words, it ignores the browser that enables DNT by default. The Apache project also seems to think that Microsoft's practice has hurt it. Fieldin indicates that intentional misuse of open standards cannot be tolerated, and DNT is considered to exist as a non-default option, because only after the recipient realizes that there is a real person to set, DNT can truly protect user privacy. Fieldin patches have aroused debate.
