1. Relationship between HTTP protocol and TCP/IP protocol HTTP persistent connections and short connections are essentially TCP persistent connections and short connections. HTTP is an application layer protocol. TCP is used at the transport layer and IP is used at the network layer. The IP protocol mainly solves the problem of network routing and addressing. The TCP protocol mainly solves how to transmit p

I recently used LVS for lb. I found that a client always suffers session loss. I used common configurations and used wlc in the balance policy, after reading this, clients with the same wlc policy may be trained on different backend machines and the session is not copied on the backend server, this will cause the client to access different servers and cause session loss. In this tutorial, you can adjust the balance policy to ensure that the same client is mapped to the same server. For more info

What is persistent connection? In fact, persistent connections are relative to common short connections, that is, to maintain the connection between the client and the server for a long time. The common short connection procedure is as follows: Connection-data transmission-close connection; The persistent connection is usually: Connection-data transmiss

The previous blog introduced its own understanding of hibernate three states, this one is mainly through the demonstration of the case to further understand the three states.Persistent Status:At this point the state persistence object is included in the management of the session, and when the thing is committed, the data is synchronized with the database, and if there is updated data will produce an UPDATE statement.Session=hibernateutils.getsession (); Tx=session.begintransaction ();//transient

Basic concepts of three states:1. Temporary identity (Transient): Also known as Free State, it exists only in memory, and there is no corresponding data in the database.Object created with new, long, not in session, the object in this state is called a temporary object;2, Persistence State (persistent): associated with the session and has corresponding data in the database.Has persisted. Added to the session cache. objects, such as those saved through

SignalR entry-level persistent connections and signalr entry-level persistence In order to maintain the development of persistent connections between the client and the server, and send data on such connections, the underlying API used to access the SignalR persistent connection provides an abstraction layer that hides the inherent complexity of the underlying la

Original Http://www.2cto.com/kf/201202/118540.html Why did you write this article? Some time ago, when studying telephony, we did not find the call to telephony initialization (makedefaphones function in phonefactory. Java) in the framework. The results are searched globally and found to be called in application phoneapp (packages/apps/phone. However, the application phoneapp is neither awakened by broadcast nor called by other services. Therefore, the Android app is started in any way, so the

Persistent connectionAndTransient connection TCP/IPProgramming has rich content. The richness of programming mainly lies in the diversity of communication methods and message formats. There are three main communication methods:: (I) Server/clientMethod 1.OneClientConnect oneServerParty, or point-to-point(Peer to Peer): 2.MultipleClientConnect oneServerThis is also the common concurrent server mode. ( 2 ) connection mode 1.

Difference Between TCP persistent connection and short connection 1. TCP connection when the network communication adopts the TCP protocol, a connection must be established between the server and the client before the real read/write operations. After the read/write operations are complete, when the two sides no longer need the connection, they can release the connection. The connection establishment requires three handshakes, And the release requires

If the communication protocol uses TCP/IP, the socket connection between the client and the middleware is very exquisite. The short connection and persistent connection should be cleverly used in applications. Purely using persistent connections or purely using short connections, Usually not reasonable. If a socket is used for a long time to relax, this will undoubtedly be a waste of middleware resources.

Requirements for persistent classesHibernate has very few requirements for persistent classes. It needs to provide a parameterless constructor so that hibernate can create persisted instances. At least the package should be visible. Provides an identity property, typically a primary key field for a database table. Each member variable needs to have a set and get method. is a non-final c

Data is the most important aspect of any computer application program. The core of a computer application is to enable someone or another computer system to access its data. In an enterprise environment, data must be not only accessible (that is, connected to the user interface and managed by a series of business rul
