ajax - Polling vs long-polling -


What is the difference between voting and long voting? What are the advantages and disadvantages? Is Ajax considered as a long time voting?

Poll: kill a URL from a customer at some interval

Long Voting: To kill the URL from the customer and keep the server connection for a period of time, in this way the server can return the connection at the time when there is a notification for his client

All AJAX is not long. Polls are used for long periods using the form of comets ()

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no.
