即使使用mathrandom，IE8仍然会缓存我的请求 [英] IE8 is still caching my requests even with mathrandom

问题描述

TLDR 即使网址中包含Math.random（），IE仍然会缓存我的请求。

TLDR IE is still caching my requests even with Math.random() included in the URL.

所以我将数学随机添加到我的网址末尾：

So I added math random onto the end of my url:

var MYKMLURL = 'http://' + host + 'data/pattern?key='+ Math.random();

我还在我的函数参数中添加了数学随机数：

I also added math random onto my function param:

window.setTimeout(RefreshPatternData, 1000, MYKMLLAYER);


           function RefreshPatternData(layer) {
               layer.loaded = false;
               layer.setVisibility(true);
               layer.refresh({ force: true, params: { 'key': Math.random()} });
               setTimeout(RefreshPatternData, 30000, MYKMLLAYER);
           }

因此请求显示为 http：// host / data / pattern？key = 35678652545 等。

它每次发出请求时都会更改。

It changes everytime the request is made.

适用于Firefox& Chrome& Safari等。但是IE8仍在缓存数据而不是更新我的图层。

It works in Firefox & Chrome & Safari etc. But IE8 is still caching the data and not updating my layer.

有关为什么会出现这种情况的任何想法？

Any ideas as to why this might be occuring?

所以我补充说：

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">

仍在缓存数据。还有什么想法？

Still is caching the data. Any further ideas?
