Preface In routing loading, I roughly introduced how to load the simplest route in rails. In this article, I will introduce how more complex named route and restful-related resources in the rails system are loaded. In order not to repeat too much pen and ink, this article will be carried out on the basis of the previous article. If you find that when reading this article separately, you are a little confus

When using a vro, you will often encounter problems, which are reflected in the route table information. When this article is about route table information, you may be wondering why I asked you to execute the IPCONFIG/ALL command. The reason for this is that you generally never read the route table information unless your machine has a problem. If you encounter a

Note: There is no source code analysis in this article. However, I think it is more useful to understand the essence than to understand the source code, because after understanding the essence, you may not need to look at the source code again, you can even write the source code. This is why the Linux kernel and Cisco websites contain a large number of documents. Introduction: routing is a core concept of the Internet. In a broad sense, it makes each node of the group exchange network independen

(i) Route Maps Characteristics: The Route maps is similar to access lists, except that Route maps can change some of the properties of the packets/routes. Use: Route maps is mainly used for redistribution and Policy Routing and BGP implementation. Realize: Policy routing send packets to

The route of ASP. NET MVC is a core of MVC application and the entry of MVC application processing, as a developer, under normal circumstances just need to define the entity, business logic, and then in the MVC controller to call, view to show, "Routing" Simply define a routing table so that when a user clicks on a link, the app can hit the correct controller, the correct action, and get the correct parameters to make the program work.But there is no

The route command for the Linux system is used to display and manipulate the IP routing table (show/manipulate the IP routing table). To achieve communication between two different subnets, you need a router that connects two networks, or a gateway that is located in two networks. In a Linux system, routing is often set up to address the following issues: The Linux system has a gateway in a local area network that allows the machine to access the Inte

can also be used to control the source address of a message. If the ACL works on the second layer, the ACL-controlled object changes from the IP address of the third layer to the MAC address of the second layer. According to the working principle of ACL, the ACL inserts an ACL-matching operation in the normal packet forwarding process, which will definitely affect the packet forwarding efficiency, if you need to control a large number of IP addresses, the ACL list will be longer, and the time r

management system, the drawback is that enterprise support is insufficient for community development drive. Arch, the pursuit of the fashion developer's first choice, the advantage is that the package update is quite fast, seamless upgrade, one installation can always work, no version of the concept, such as Ubuntu, said the professional point called rolling upgrade, keep your system must be up to date. The shortcomings are obviously easy to see and unstable. Installing the configuration at

placed in order, the virtual function address of the parent class is in front. So after the assignment, the address of the virtual function does not change, but the subclass overrides the virtual function in the parent class, so the function in the virtual function table is called, regardless of the object being called.Do not understand the students, please Baidu virtual function table, the above are described in detail and diagram.This article from "Very blog" blog, reproduced please contact t
