Founder of the cookie disgusting, finally found, in 1993 the grandfather ------- Lu Lu -!. Monterey invention. Slowly look down, you will be more understanding and session cookie.
A: HTTP socket stateless protocol and two-way communication
Stateless protocol refers to the protocol for transaction processing without memories. If the lack of state means that the subsequent processing required in front of the information, it must be retransmitted, which may result in the amount of data transmitted for each connection is increased. On the other hand, when it does not require previous information in response to a faster server. Unlike Http protocol to establish a socket connection of two terminals, both sides can communicate with each other, http client can only be access to relevant information by requesting the content or file server.
http protocol This feature has advantages and disadvantages, the advantage of the liberation of the server, each request "go beyond" the connection will not cause unnecessary occupation, the disadvantage is that each request would transfer large amounts of duplicate content information.
Two: HTTP development is a process of continuous self-improvement
1.web the beginning, just a simple page views, what to check to see what just fine. No interaction .
2. Later interaction is required, you need to log on and so on. On the broad session up. Generalized session is the idea, is a session control of strategic pursuit .
3. Keep a session narrowly data to control the answer, site traffic increases, each user's session are saved on the server, the server can not stand , 1993 to engage in out of cookie technology. cookie is real, is generalized session control tactics to achieve .
4. url may be rewritten to achieve control generalized session. Is a solution different from the cookie
5. narrowly session is stored in the server, cookie stored in the client. Generalized session itself is a pursuit. Hey, tell, broad narrow, very ignorant forced to make white.
Three: in the end is the conventional cookie, or some first session

2.session background
Baidu for a long time, check more than one hundred search results, Baidu Encyclopedia also checked, or finding out, session mechanism proposed time . However, it is determined that the existing concept of session, only later to realize the session.
Hang force Baidu! Deceptive learn SEO, deceptive sites do MIP reconstruction, deceptive search results!
3. There are some other solutions, such as token, jwt and so on, these are the differences Road and surgery.
Again, web immortal, session forever!
Check the information for a long time, know almost, csdn, Baidu Encyclopedia, and so on, lessons, certainly for your help. There is not too much detail, but the idea to figure out, you know why it is, I think it is more important!
