jquery - $.ajax设置缓存: What does that mean in jquery code

Question

今天我在 Jquery 代码中观察到以下内容:

$.ajaxSetup({ cache: false });

这是什么意思？如果缓存的值变为 True 会发生什么。

提前谢谢

阅读jQuery.ajax()

cache (default: true, false for dataType 'script' and 'jsonp') Type: Boolean If set to false, it will force requested pages not to be cached by the browser. Note: Setting cache to false will only work correctly with HEAD and GET requests. It works by appending "_={timestamp}" to the GET parameters. The parameter is not needed for other types of requests, except in IE8 when a POST is made to a URL that has already been requested by a GET.
