HTML5 Manifest是否有大小限制？ [英] Is there a size limit for HTML5 Manifest?

问题描述

我一直在研究HTML5清单，但我不清楚是否有使用清单进行缓存的文件大小限制。

例如，如果我想让多个音频文件脱机可用，这可以通过使用清单来实现吗？或者它真的只适用于小图片和文字？

解决方案

据我所知规范未指定对象或整个缓存的最大大小，但是例如Firefox默认情况下允许总共50MB的缓存文件。这意味着高速缓存确实针对小文件（html，css，js，图像）进行了优化，而不是针对大文件（视频，音频......）进行优化。

I have been looking into HTML5 manifest but I am unclear as to whether or not there is file size limit for caching using the manifest.

For example if i wanted to make several audio files available offline would this be achieved using manifest? or is it really only for small images and text?

解决方案

as far as i know the spec doesn't specify a maximum size for an object or for the entire cache, but e.g. firefox has a preference which by default allows a total of 50mb worth of cache-files. that implies that indeed the cache is optimized for small files (html, css, js, images) and not for big files (video, audio, ...).
