问题描述
是否可以向我展示带范围请求的示例http会话。
我的意思是请求和响应标头是什么？
Is it possible to show me a sample http session with range requests.I mean what would be the request and response headers?
推荐答案
以下交换是在Chrome和静态网络之间进行的服务器，检索MP4视频。
The following exchange is between Chrome and a static web server, retrieving an MP4 video.
初始请求 - 视频。请注意 Accept-Ranges 响应标头，以指示服务器具有范围标头支持：
Initial request - for the video. Note the Accept-Ranges response header to indicate the server has range header support:
GET /BigBuckBunny_320x180.mp4
Cache-Control: max-age=0
Connection: keep-alive
Accept-Language: en-GB,en-US,en
Host: localhost:8080
Range:
Accept: text/html,application/xhtml+xml,application/xml,*/*
User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.7 ...

200 OK

范围hea检测到之前的响应中的后续请求 - 具有开放式范围的后续请求以确认支持。响应返回206状态和 Content-Range 标头，以指示响应正文中存在的字节：
Range header in previous response detected - subsequent request with open-ended range to confirm support. Response returns a 206 status and Content-Range header to indicate the bytes present in the response body:
GET /BigBuckBunny_320x180.mp4
Connection: keep-alive

捕获文件末尾的后续范围请求（可能捕获尾随元数据）：
Subsequent range request to capture the end of the file (probably to capture trailing metadata):

Accept-Language: en-GB,en-US,en

用户点击视频进度条超出下载范围 - 发出范围请求以从所选位置开始播放：
User clicks in the video progress bar beyond the downloaded range - a range request is issued to begin playing from the selected position:
