Question:
b' Why does Google prepend while(1); to their (private) JSON responses?For example, here\'s a response while turning a calendar on and off in Google Calendar:while (1);[ [\'u\', [ [\'smsSentFlag\', \'false\'], [\'hideInvitations\', \'false\'], [\'remindOnRespondedEventsOnly\', \'true\'], [\'hideInvitations_remindOnRespondedEventsOnly\', \'false_true\'], [\'Calendar ID stripped for privacy\', \'false\'], [\'smsVerifiedFlag\', \'true\'] ]]]I would assume this is to prevent people from doing an eval() on it, but all you\'d really have to do is replace the while and then you\'d be set. I would assume the eval prevention is to make sure people write safe JSON parsing code.I\'ve seen this used in a couple of other places, too, but a lot more so with Google (Mail, Calendar, Contacts, etc.) Strangely enough, Google Docs starts with &&&START&&& instead, and Google Contacts seems to start with while(1); &&&START&&&.What\'s going on here?
