HTTP Request and Response

The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed hypermedia

information systems It is a generic, stateless protocol, which can be used for many tasks beyond its use for hypertext A feature of HTTP is the typing and negotiation of data representation, allowing systems to be built independently of the data being transferred

The first version of HTTP, referred to as HTTP/0.9, was a simple protocol for raw data transfer across the Internet HTTP/1.0, as defined by RFC 1945 improved the protocol by allowing messages to be in a MIME-like format, containing meta-information about the data transferred and modifiers on the request/response semantics The current version HTTP/1.1, first defined in RFC 2068 and more recently in RFC 2616, made performance improvements by making all connections persistent and supporting absolute URLs in requests

URL Request Protocols

A URL is a pointer to a particular resource on the Internet at a particular location and has a standard format

as follows:

Protocol Servername Filepath

In order, the three elements are the protocol used to access the server, the name of the server and the

location of the resource on the server For example:

http://www.mydomain.com/

https://www.mydomain.com:8080/

ftp://ftp.mydomain.com/example.txt mailto:me@world.com

file:///c:|Windows/win.exe

Trang 48

1060

The servername and filepath pieces of the URL are totally dependent on where files are stored on your server and what you have called it, but there are a standard collection of protocols, most of which you should be familiar with:

❑ http: Normal HTTP requests for documents

❑ https: Secure HTTP requests The specific behavior of these depends on the security certificates and encryption keys you have set up

❑ JavaScript: Executes JavaScript code within the current document

❑ ftp: Retrieves documents from an FTP (File Transfer Protocol) server

❑ file: Loads a file stored on the local (Client) machine It can refer to remote servers but specifies no particular access protocol to remote file systems

❑ news: Used to access Usenet newsgroups for articles

❑ nntp: More sophisticated access to news servers

❑ mailto: Allows mail to be sent from the browser It may call in assistance from a helper app

❑ telnet: Opens an interactive session with the server

❑ gopher: A precursor to the World Wide Web

This book exclusively deals with the first five of these

Method Request- URI Protocol

For example,

GET /index.html HTTP/1.0

uses the GET method to request the document /index.html using version 1.0 of the protocol We'll come

to a full list of HTTP Request Methods later

Next, the client sends optional header information to the server about its configuration and the document formats it will accept All header information is sent line by line, each with a header name and value in the form:

Trang 49

Finally, after sending the request and headers the client may send additional data This data is mostly used

by CGI programs using the POST method This additional information is called a request entity Finally a blank line (\r\n\r\n) terminates the request A complete request might look like the following:

GET /index.html HTTP/1.0 Accept: */*

Connection: Keep-Alive Host: www.w3.org User-Agent: Generic

OPTIONS Used to query a server about the capabilities it provides Queries can be general or

specific to a particular resource

GET Asks that the server return the body of the document identified in the

Request-URI

HEAD Responds similarly to a GET, except that no content body is ever returned It is a

way of checking whether a document has been updated since the last request

POST This is used to transfer a block of data to the server in the content body of the

request

PUT This is the complement of a GET request and stores the content body at the

location specified by the Request-URI It is similar to uploading a file with FTP

DELETE Provides a way to delete a document from the server The document to be deleted

is indicated in the Request-URI

TRACE This is used to track the path of a request through firewalls and multiple proxy

servers It is useful for debugging complex network problems and is similar to the traceroute tool
