ajaxSetup is global.
A solution with less potential side-effects would just use $.ajax
directly, specifying the cache option along with url, dataType and
success:
$.ajax({
cache: true,
dataType: "json"
url: "something.js"
success: callbackFunc
});
From the code it looks like the documentation is wrong: The default
for the cache option is false. Can someone confirm that?
