HTTP允许浏览器或其他用户代理与Internet 上的不同资源进行通信：为此，浏览器既需要资源的身份，又需要资源的位置。这两位信息由URI描述。

识别WebURI上的资源以及如何访问Web上的资源。数据URIs特定种类的URI，数据URI，将资源本身嵌入到标识符中。在www和非www URL之间选择使用www前缀域还是非www域名，本文解释了选择的后果以及如何制作它.MIME TypesMIME媒体类型定义了特定资源的文档类型。本文介绍了在Web上使用的语法和最有用的MIME类型。完整的MIME类型列表适用于Web开发人员的MIME类型综合列表./分离资源的标识和位置：Alt-Svc标头如果标识和位置都使用URL描述，它们是两个不同的概念，有时可以区分它们。本文介绍Alt-Svc标题。
