Asp. Net implements Http persistent connection push, and asp.net implements http Let's talk about how to help a friend develop smart home and build a cloud platform. The main function of a mobile phone is to forward the commands of a mobile client and an intelligent network in an external LAN environment. Currently, a stable Socket version is available, but considering that future expansion and performance indicators need to be changed to the form of

One, persistent object lifecycleafter the application has used the Hibernate framework, the persistent objects created will undergo a complete lifecycle to perform the operation of the database, in which the main three states are transient (Transient), persistent (persistent), and out of control (detached). The convers

August 31, 2007 Many applications, such as monitoring, instant messaging, and instant quotation systems, need to send changes in the background to the client in real time without the need for the client to refresh and send requests continuously. This article first introduces and compares common "server push" Solutions, focuses on the two "server push" Solutions of comet-using HTTP persistent connections and without the need to install plug-ins

1. Preface Apache Mina is an excellent project organized by Apache. Mina is the abbreviation of multipurpose infrastructure for networkapplications. It is a network application framework that helps users easily develop high-performance and high-reliability network applications. This article describes how to use Apache mina2.0 to implement TCP persistent connections and short connection applications.2. system introduction 2.1 System Framework The entir

One, persistent connectionWhat is a persistent connection? for the HTTP protocol, it is based on the request response model, when the client sends a request to the server, first establishes an HTTP connection, and the server responds to the client data, and the connection is closed.When the client sends the next request, the HTTP connection needs to be re-established : A request response needs to consume an

From: Http://blog.csdn.net/camel_flying/article/details/6056910 1. persistent connection and short connection: Persistent connection: The client establishes a connection with the server. After the connection is established, the connection continues to open and then sends and receives packets. In this mode, communication connections always exist.This method is usually used for P2P communication. Trans

HTTP persistent connections and short connections are essentially TCP persistent connections and short connections. HTTP belongs to the application layer protocol and uses TCP protocol at the transport layer. 1. relationship between HTTP protocol and TCP/IP protocol HTTP persistent connections and short connections are essentially TCP

Specifically, requests on the TCP layer (as long as they follow the protocol established on the TCP layer) are parsed, and then distribute them to specific services. One problem encountered in this process is the persistent connection problem in HTTP. I che

One or three States (Transient, Persistent, and Detached) have three states in Hibernate. With deep understanding of it, we can better understand the running mechanism of hibernate. At the beginning, we didn't pay much attention to these concepts, later I found it important. Better understanding of the relationship between hibernate, JVM, and SQL. For JAVA objects that require persistence, there are three states in their lifecycles and they are conver

Regardless of the programming language, almost always have to deal with a variety of databases. However, it is well known that the connection between the program and the database is a resource-intensive thing, so many experts and predecessors in the field of programming technology envision and propose various solutions to reduce unnecessary waste of resources, thereby increasing the access of the program to the database.Among the many connectivity scenarios for programs and databases, the most w

Persistent connection and short connection A persistent connection means that multiple data packets can be sent continuously over a TCP connection. If no data packet is sent during TCP connection persistence, both parties need to send a detection packet to maintain this connection, generally, you need to maintain it online.A short connection is a TCP connection established when both parties have data intera

When developing php-based im communication tools on the server (web or app may be used), generally, http is used for logon and registration, this part can be implemented through nginx or apache. persistent connection message push. the socket persistent connection must be independent on the server... when developing php-based im communication tools on the server (web or app may be used), generally, http is u

WEB clients often open connections to the same site. For example, most inline images on a Web page are usually from the same Web site, and a significant portion of hyperlinks to other objects usually point to the same site. Therefore, an application that initializes an HTTP request to a server is likely to make more requests to that server in the near future. This property is referred to as site locality locality.Therefore, http/1.1 (and the various enhanced versions of http/1.0) allow the HTTP
