使用“传输编码:分块"，在浏览器开始渲染之前必须发送多少数据? [英] Using "transfer-encoding: chunked", how much data must be sent before browsers start rendering it?

问题描述

所有浏览器在开始呈现您通过网络刷新到它的部分 http 响应之前，都会等待一些内容(有时也是一些时间) - 但要等待多少?

解决方案

我今天对此做了一些研究，一个 url 端点接受让我配置块大小和间隔.

<前>Mac:文本/html:图像/jpeg:卷曲 7.24.0 4096 字节火狐 17 1024 字节 1886 字节Chrome 26.0.1410.65 1024 字节 1885 字节Chrome 29.0.1524.0 8 字节 1885 字节Safari 6.0.4 (8536.29.13) 1024 字节整个文件视窗 XP:IE8 256 字节Chrome 27.0.1453.94 1024 字节火狐 21 1024 字节Opera 12.15 128 bytes AND 3s 已经过去Windows 7的IE9 256 字节视窗 8:IE10 4096 字节

All browsers wait for some content (and sometimes some amount of time, too) before they start rendering a partial http response you have flushed to it across the network - but how much?

解决方案

I did some research on this today with an url endpoint accepting letting me configure chunk sizes and intervals.

Mac:                       text/html:     image/jpeg:
curl 7.24.0                4096 bytes     
Firefox 17                 1024 bytes     1886 bytes
Chrome 26.0.1410.65        1024 bytes     1885 bytes
Chrome 29.0.1524.0         8    bytes     1885 bytes
Safari 6.0.4 (8536.29.13)  1024 bytes     whole file

Windows XP:
IE8                        256  bytes
Chrome 27.0.1453.94        1024 bytes
Firefox 21                 1024 bytes
Opera 12.15                128  bytes AND 3s have passed

Windows 7
IE9                        256  bytes

Windows 8:
IE10                       4096 bytes
