Before continuing to analyze the source code, it is necessary to familiarize yourself with the UML Model diagram of the connector. Otherwise, in the face of the intricate dependency, it is inevitable that people cannot clarify their clues.
First, familiarize yourself with the following UML Model:

As mentioned in the introduction, Catalina has two main modules: connectors and containers. In this chapter, you will write a connector that can create better request and response objects to improve the program in Chapter 2nd. A connector compliant with Servlet 2.3 and 2.4 specifications must create javax. servlet. http. httpservletrequest and javax. servlet. http. httpservletresponse and pass them to the s
The receiver/connector mode is designed to reduce the coupling between connection establishment and service execution after the connection is established. For example, in the WWW browser, the service or "actual work" performed is to parse and display the HTML page received by the client's browser. Connection establishment is secondary and may be accomplished through BSD sockets or some other equivalent IPC mechanism. Using these patterns allows progra
Before discussing the details of connectors and their role in the overall ActiveMQArchitecture, it ' s important to understand connector URIs. Uniform Resource Identifiers(URIs), as a concept, aren ' t new, and you ' ve probably used them over and over againWithout realizing it.

In the case of this level of load, you may not need to put the Web server before Tomcat. But there is a second reason to do so, and that is to create a control area (demilitarized zone). Placing a Web server on a host is equivalent to inserting a quarantine zone (neutral zone) between the company's private network and the Internet or other external public networks, which allows the application on Tomcat to secure access to other private resources, as well a

If you can use them in pairs without considering the connection direction, and the connection is simple and convenient, it will be helpful for Gigabit Ethernet connections. Therefore, many cable cabling manufacturers have introduced various connectors to meet this application. This new optical cable
