Use the most a kind of procotol on the HTTP the Internet, all WWW files all must be observed this standard.How http protocol has defined in the webpage conversation procedure Web client from the Web server request Web page, and how server to send the Web page to client, and http protocol has adopted the request model.In the webpage conversation procedure of one whole, will follow http protocol between Web browser and the Web server and accomplish following 4 steps:
(1) sets up the webpage session connection;
Before carrying out the webpage session; Web browser at first will connect through network and Web server, and this connection is accomplished through TCP, and this agreement and IP agreement make up Internet jointly; Be famous TCP/IP protocol suite, so Internet b referred to as the TCP/IP network again.HTTP is the application layer protocol more higher level than TCP, according to rule, has only lower layer protocol to set up ability afterwards, just can carry out the more connection of layer protocol, therefore, at first will set up TCP and connect, and the port numbers that general TCP connects is 80;
(2) Web browser sends HTTP web-page requests bag to Web server;
In case set up the TCP connection, Web browser is asked the network address of visiting according to the user, will send HTTP web-page requests bag to Web server, and HTTP web-page requests bag comprises: the method for request, URL, protocol version, request head and request msg.Wherein, the requesting method of http protocol has GET, POST, HEAD, PUT, DELETE, OPTIONS, TRACE, CONNECT, and the general GET method of only using during web page browsing; URL (Uniform Resource Locator; URL) is the resource addresses of standard on the internet; URL is made up of agreement, domain name, request address three parts; Intactly URL is unique has confirmed a requested resource; Can be the page, content module, file or multimedia resource etc., such as browse Netease's homepage=＞sports channel=＞Division A League Football Matches of Italy, their URL is followed successively by http://www.163.com/=＞http://sports.163.com/=＞http://sports.163.com/yj/.To forming, every row is a pair of by keyword/value for the request head, and keyword is separated with English colon ": " with value.Request head announcement server is relevant for the information of client-requested, and typical request header has:
User-Agent: the browser type that produces request;
