Is it possible to unload an element and store it in a cookie?

Question

AJAX

I unload a div-element on the main page of the site, which contains an important notification for the user. The server can be contacted no more than 2 times per minute, otherwise the user will receive an IP block.

I use the code:

$('#push-add').load('/lk.html #push');

Tell me how to limit the number of downloads of this script and at the same time save the downloaded element in #push-add on the page?
