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:
['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
What's going on here?
