                   var $form = $(this);

                   if ($form.data('submitted') === true) {

          $('form :submit').click(function () {
               $(this).prop("disabled", true).closest('form').append($('<input/>', {
                   type: 'hidden',
                   name: this.name,
                   value: this.value


Thank you, this will stop accidental double submitions by innocent users, but I was thinking about server side prevention to stop attackers, racing attacks etc (e.g. making sure an external API call doesn't get executed twice because of double submition or racing attacks)

PHP Code:

and now any simultaneous viewers of the page - are all hitting the cached version which comes back instantly. your database is completely untouched and its resources saved for the more critical tasks.

This performance tip was awesome thank you sir Heart basically even setting this to 1 will reduce the pressure on the database by a lot
