WebLogic domain, Management Server, managed server, cluster and Machine Basics 1. Domain? What is it? – is a logically managed WebLogic server group that is managed as a whole? What's in the domain? – Server – Server cluster – machine?

Implement CORS requests in Java and cross-origin in JavaProblem When you use the frontend and backend separation mode to develop a project, you will often encounter this problem-you cannot obtain server data across domains. This is caused by the same-source policy of the browser and is designed for security. Today, the development mode of separation from the front and back ends is favored. front-end and back-end projects are often developed in differe

Let's talk about their advantages: Data servers are separated from application servers and generally use SQL services. In this case, data security is increased. databases on the same LAN are not connected to the Internet and only serve application servers. The application server is only responsible for access, and the data server is only responsible for applicat

In layman's terms, Web servers send pages to allow browsers to browse. However, the application server provides the methods method that client applications can call ).

Label: article reprint address:Http://freewind.me/blog/20140327/2456.htmlProblem when using AJAX to request data from a page under another domain name, you encounter cross-domain issues. Another domain name must be added to the Access-control-allow-origin header in response in order for the former to get the data successfully. Is that the right thing to say? If yes, then what is the process? How can cross-domain be counted across domains? Protocol

Analysis of Ajax cross-origin principle and implementation analysis in JQueryThe emergence of AJAX allows the web page to be refreshed locally by performing a small amount of data exchange with the server in the background. However, for security reasons, ajax does not allow cross-origin communication. If you try to request data from different domains, an error will occur. If you can control the remote serve
