HTTP Learning Notes

1.Http gives each Web-transmitted object a MIME (multipurpose Internet Mail Extension) type data format label that describes and marks the multimedia content.

2.URI (Uniform Resource Identifier): There are two forms of URL and urn.

The three parts of 3.URL:

• Scheme, the type of protocol used to access the resource. such as HTTP/
• The server's Internet address. such as www.baidu.com
• The rest of the section specifies a resource on the Web server.

4.URN (Uniform Resource name): Used as a unique name for a specific content, regardless of where the resource resides. In the experimental phase.

5. An HTTP transaction consists of a request command and a response result. This communication is done through a formatted chunk of HTTP messages (HTTP message).

6.HTTP message: Request message and Response message. Three parts:

• Starting line: Request message: Description of what to do; Response message: Explain what happened
• Header field: Each header field contains a first name: a value. End with a blank line
• Subject

7.TCP (transmission Control Protocol) transmission protocol.
