Transfer-Encoding vs Content-Encoding

  • Transfer-Encoding - 可动态修改 - 传输层
  • Content-Encoding - 不要动态修改 - 业务逻辑层
    • 大多客户端实现都使用 Content-Encoding 检测压缩

# 返回 content-encoding: gzip
curl -H 'Accept-encoding: gzip' -I https://s.wener.me

curl -H 'Accept-encoding: zstd, br, gzip, deflate' -I https://s.wener.me

  • 302 Found / Moved Temporarily
    • 临时,还会再请求
  • 303 See Other
    • 特定语义
  • 307 Temporary Redirect
    • 请求重发
    • 支持 POST
  • 308 Permanent Redirect
    • 类似 301 但不允许修改 method

HTTP SEARCH/QUERY Method

  • GET 支持缓存,但不能携带 Body 请求
  • POST 可以用作查询,但不能缓存
  • 目前应该会支持 QUERY 方法

HTTP SEARCH is a new HTTP method, for safe requests that include a request body. It's still early & evolving, but it was recently adopted as an IETF draft standard, and it's going to add some great new tools for HTTP development everywhere.
