Cookies are widely used in Web applications to maintain the state between browsers and servers. Unfortunately, this feature is not supported in the Java ME platform. Therefore, to maintain the state of the client and server side, you must use a URL rewrite method. URL rewriting is a hassle to work with, so it's a good idea to study the cookie principle and implement cookies on the Java ME platform. First, let's look at the principle of cookies. When t

One, what is a cookie?
cookies are generated by the server side, always stored in a small piece of text information on the client, when you browse the Web page, the browser will store it on the hard disk, the next time you visit the same address, as long as the cookie is not invalidated, The browser sends its information to the server again.
Therefore, cookies are accompanied by a user request and the pa

1. Status of the storage client
A question leads to today's content, such as the site's shopping system, where users store the information they purchase. Because the HTTP protocol is stateless, which means that each client accesses a server-side resource, the server does not know who the client is, and therefore requires session technology to identify the state of the client. Session technology is to help the server remember the client state (client-side) 2. Session Technology

I. Introduction of cookies and sessionCookies are not part of the HTTP protocol, and because the HTTP protocol is not able to maintain state, we need to "keep state" in reality, so cookies are born in such a scenario.A cookie works by creating content from the server, saving it locally when the browser receives it, and automatically bringing a cookie when the browser accesses it, so that the server can tell
Set Cookies
Each cookie is a name/value pair, and you can assign a string such as the following to Document.cookie:
Document.cookie= "userid=828";
If you want to store more than one name/value pair at a time, you can use a semicolon plus a space (;) To separate, for example:
Document.cookie= "userid=828; Username=hulk ";
You cannot use semicolons (;), commas (,), Equals (=), and spaces in the name or value of a

Different operating systems may not have the same place to store cookies. different browsers store cookies in their own separate spaces and do not interfere with each other . in my Windows7, IE8, for example, a
Cookie IntroductionAs we all know, the Web protocol (that is, HTTP) is a stateless protocol (HTTP1.0). A Web application consists of a number of web pages, each of which has a unique URL to define. The user enters the URL of the page in the address bar of the browser, and the browser sends the request to the Web server. For example, the browser sends two requests to the Web server and requests two pages. The requests for the two pages were using two s

Common session tracking techniques are cookies and sessions. Cookies can save temporary data on the client by identifying the user in the client record information.Since the advent of Cookie technology, it has become a major issue for Internet users and web

Therefore, when a request is sent to the Web server, whether it is the first visit or not, the server treats it as the first visit. Such a bad thing can be imagined. To make up for thisDefect.

1. the HTTP protocol itself is stateless.
We need to transmit information over HTTP to access the Internet. For example, if you type "www.sanyalanhua.com" in your browser and press enter, you will find that the website will change to "http: // www.sanyalanhua.com" because the web page is based on the http protocol. The http protocol does not record websites that users often access, their hobbies, and their ID accounts an

Cookie and Sessioncookie and session understanding
The HTTP protocol itself is stateless, which is consistent with the HTTP protocol's original purpose, the client simply needs to request to the server to download some files, both the client and the server do not need to record each other's past behavior, each request is independent, Like the relationship between a customer and a vending machine or an ordinary (non-membership) hypermarket.
