httpIntroduction

httpd is the main program for the Apache Hypertext Transfer Protocol (HTTP) service. is designed as a stand-alone background process that creates a pool of child processes or threads that process requests

Process for a complete HTTP request

(1) Establishing or processing connections

(2) Receiving requests

(3) Processing requests

(4) Access to resources

(5) Building response messages

(6) Send Response message

(7) recorded in the log

HTTP protocol Request method

  • GET Requests the specified page information and returns the resource principal

  • HEAD is similar to a GET request except that there is no specific content in the response returned to get the HTTP header

  • POST submits form data to the specified server for processing requests. The request message principal species contains the content of the data information to be passed. a POST request may result in the creation of new resources and / or modification of existing resources.

  • PUT a data resource that uploads from the client to the server to replace the contents of the specified document.

  • the delete request server deletes the specified resource.

  • The Connect http/1.1 protocol is reserved for proxy servers that can change connections to pipelines.

  • The OPTIONS allows clients to view server performance.

http Protocol Response

The HTTP response is also made up of three parts, namely the status line, the message header, the response body

1, the status line format is as follows
Http-version Status-code Reason-phrase

whichHttp-versionrepresents the serverHTTPversion of the ProtocolStatus-coderepresents the response status code sent back by the serverReason-phraserepresents a text description of the status code.
The status code has three digits that make up the first number defines the category of the response and has five possible values
1xxinstruction Information--indicates that a request has been received to continue processing
2xxSuccess--indicates that the request has been successfully received, understood, accepted
3xx redirect--further action is required to complete the request
4xxClient Error--request has a syntax error or the request is not implemented
5xxserver-side error--the server failed to implement a legitimate request
common status codes, status descriptions, descriptions
$ OK//Client Request succeeded
Request//the client request has a syntax error that cannot be understood by the server
401 Unauthorized//request Unauthorized This status code must andWww-authenticateheader fields used together
403 Forbidden//The server receives the request but refuses to provide the service
404 Not Found//Request resource does not existegThe error is entered.Url
Internal Server Error//Unexpected error occurred on server
503 Server Unavailable//the server is currently unable to process client requests and may return to normal after a period of time
