Mobile Safari 5mb HTML5应用程序缓存限制？ [英] Mobile Safari 5mb HTML5 application cache limit?

问题描述

在我的测试中，越来越明显的是，Mobile Safari的HTML5应用程序缓存实现的大小限制为5mb。

有人知道如何规避或提高这个吗？有一些我应该知道的未曝光元标记吗？我必须为离线应用缓存一些视频内容，5mb还不够。

解决方案

我试着写一个使用此清单进行简单测试：

  CACHE MANIFEST 
＃2010-06-20：v4 
 
 http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js

此缓存将需要11.4MB的存储空间。

当我打开一个包含该清单文件的页面时，它会这样说：该网站需要使用高达25MB的存储空间，你想增加本地存储吗？。

我认为我得到了iOS的方式：

• 本地只有5MB存储（包括HTML5应用程序缓存）


• 如果您的网站需要更多内容，Safari需要用户同意某些软件包（最多10MB或25MB或更多...） b $ b

希望对你有用。

It's becoming evident in my testing that there's a 5mb size limit on Mobile Safari's implementation of HTML5's application cache.

Does anyone know how to circumvent or raise this? Is there some unexposed meta tag that I should know about? I have to cache some video content for an offline app and 5mb is not going to be enough.

解决方案

I tried to write a simple test with this manifest:

CACHE MANIFEST
# 2010-06-20:v4

http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
http://peach.blender.org/wp-content/uploads/big_big_buck_bunny.jpg

This cache will need 11.4MB of storage.

When I open a page include that manifest file, it say something like that: "This website require to use up to 25MB of storage, do you want to increase local storage?".

I think I got what the way iOS do:

• You only have 5MB for local storage (include HTML5 application cache)
• If your web need more, Safari need user's agreement for some packages (up to 10MB, or 25MB, or more...)

Hope that useful for you.
