禁用ExtJs应用程序的缓存 [英] Disable caching for ExtJs app

问题描述

我们有一个使用Sencha cmd 5.0.1.231构建的ExtJS 5.01应用程序。

We have a ExtJS 5.01 app built with Sencha cmd 5.0.1.231.

我们面临的问题是浏览器似乎缓存了我们应用程序的旧版本。在我们的应用程序发布时，在查看Chrome上的网络流量时，我可以看到app.js，app.css文件都附加了_dc = {timestamp}。现在，这告诉我，每当我的应用程序的新版本被发布（更新这个时间戳）时，浏览器应该得到一个新的版本。但是，似乎有时候仍然旧版本得到了服务。

The issue we are facing is that browsers seem to cache the old version of our application. On looking at the network traffic on chrome when our application is served, i can see that app.js, app.css files all have ?_dc={timestamp} appended to them. Now, that tells me that every time a new version of my app is released (which updates this timestamp), the browsers should get a new version. But it seems like sometimes still the old version get served.

还有什么我需要做超级缓存吗？

Is there anything else i need to do bust cache?

谢谢

推荐答案

我不明白为什么有时浏览器缓存文件，即使默认情况下禁用缓存。我甚至强制框架尽可能使用缓存，通过将这个安全的代码放在我的 app.js 中：

I don't get it why "sometimes" the browser is caching your files, even when caching is disabled by default. I even force the framework to use cache whenever possible, by putting this peace of code in my app.js:

Ext.Loader.setConfig({
    enabled: true,
    disableCaching: false
});

在开发我开发我的DevTools并设置 禁用缓存（当DevTools打开时） 。这不允许Chrome缓存文件。

While developing I open up my DevTools and set Disable cache (while DevTools is open). This will not allow Chrome to cache files.

但可能是在您的 app.json 中，您强制通过设置更新或appcache，将缓存到本地存储空间。检查您的本地存储和您的app.json以验证。

But it could be that in your app.json you are forcing "caching" into your local storage by setting "update" or "appcache". Check your localstorage and your app.json to verify.
