Setting the cache in jQuery $.post() to be false?

Question

I have this code:

$.post("php/tagNotifUnsub.php", $("#tagNotifUnsub").serialize(), function(){ 
            $('#tagSubDiv').load('tags.php #tagSubDiv', function(){$( "button, input:submit, input:button, a#jql, input:radio" ).button();});      
        });

I understand that $.post is just another name for $.ajax. And I know $.ajax has caching on by default. I want it to be uncached. How can I do that?

Answer 1

$.post is not cached.

Pages fetched with POST are never cached, so the cache and ifModified options in jQuery.ajaxSetup() have no effect on these requests.

Answer 2

Partly right, Daniel A. White!

On devices running iOS6 and Safari, POST is also cached.

What you can do is the following:

$.ajaxSetup({
   type: 'POST',
   headers: { "cache-control": "no-cache" }
});
