What happens after we type" www.baidu.com "

What happens after we type "www.baidu.com"?

First the browser creates a HTTP GET request like this:

GET/index.html HTTP/1.1

Host:www.baidu.com

User-Agent: GoogleChrome/......

.......

Then the HTTP GET is sent to the server,and the server finds the page index.html of baidu. Then the sever generates an HTTP response like this:

HTTP/1.1 200 OK

Set-Cookie:.....

....

<html>

<head>

<meta http-equiv="Content-Type" content="text/html;charset=gb2312"><title>百度一下,你就知道     ....

....

The HTTP response is sent to the browser ,then the browser renders the HTML .Up to this , we can see the  home page of baidu on the browser.
