Answer 1

for prevent multiple ajax request in whole site. For example: If use ajax request in other ajax page, Using ajax in php loop, etc, Give you multiple ajax request with one result. I have solution:

instead of

$(document).ready(function(){ ...  });

on the main index.php page. Its will be prevent all multi request. :)
