processingFor example, to illustrate the role of the agent: Suppose we want to invite a star, then not directly connect the star, but contact the star's agent, to achieve the same goal. A star is a target, and he only takes charge of the program in the event, and other trivial things to his agent (broker) To solve. This is an example of the idea of acting in reality.The diagram shows the following:The key point of the proxy mode is: The
Reverse proxy is also a kind of important technology that can help to realize the static website, today I will talk about the subject of reverse proxy. So first we need to understand what the reverse proxy is. And the reverse proxy is the forward
cases, more and more websites are using proxy acceleration. For example, Sina and Sohu news all use squid as proxy and use multiple servers for traffic distribution. Squid itself is similar to a transparent proxy and will send "http_x_forwarded_for". http_x_forwarded_for includes the customer's IP address. If the cust
The company uses Telecom optical fiber and allocates five IP addresses. For ease of use, the optical fiber of the optical cat is directly connected to the switch.
The outside and inside networks of the Cisco 2911 router are all wired from the vswitch.
Because the Cisco router enables proxy-ARP by default, when outside receives the broadcast ARP information, because the inside CIDR Block and the broadcast C
cases, more and more websites are using proxy acceleration. For example, Sina and Sohu news all use squid as proxy and use multiple servers for traffic distribution. Squid itself is similar to a transparent proxy and will send "http_x_forwarded_for". http_x_forwarded_for includes the customer's IP address. If the cust
The company built a stable proxy pool service for distributed deep web crawlers to provide effective proxy services for thousands of crawlers, ensuring that all crawlers receive valid proxy IP addresses for their websites, this ensures the fast and stable operation of Crawlers. Therefore, we want to use some free resou
Nginx reverse proxy, the IP obtained in the application is the IP of the reverse proxy server, the domain name is also the reverse proxy configuration URL of the domain name, to solve the problem, you need to add some configuration information in Nginx reverse
In nginx reverse proxy, thinkphp and php cannot obtain the correct Internet ip address. nginxthinkphp
When a user needs to obtain the user's ip address to send a text message, tp always obtains the Intranet ip Address: 10.10.10.10.

1. The use of proxy IPs:When crawling Web pages, some target sites have anti-crawler mechanisms, for frequent visits to the site and regular access to the site behavior, will collect the shielding IP measures. At this time, you can use proxy IP, shielded one on the other IP.
In the Linux environment, the strong-reverse proxy of Nginx is used. As a result, the IP obtained by request. getRemoteAddr () is the IP address of the proxy server of the company, and the log records are seriously inaccurate!We all know that the method for obtaining the Client IP
The external java/php server-side acquisition client IP is the same: pseudo-code:1) IP = Request.getheader ("x-forwarded-for") can be forged, refer to Appendix A 2) If the value is empty or the array length is 0 or equal to "unknown", then:IP = request.getheader ("Proxy-client-ip")3) If the value is empty or the array

First, the agent mode
Provides an agent for an object to control access to this agent. The proxy class and the delegate class have a common parent or parent interface, so that proxy class object substitution can be used wherever the delegate class object
A Brief introduction: WebProxy: HTTP proxy settings.
Official explanation: The WebProxy class contains WebRequest instances to determine whether proxy settings are used to send requests using a WEB proxy. You can specify global Web proxy settings in your computer and application configuration files, and your applicati
Java static ProxyStatic proxies are often used to augment legacy business logic. For example, a class that holds a two-party package and calls some of these methods. Then for some reason, such as logging, printing method execution time, but it is not good to write these logic to the two-party package method. So you can create a proxy class implementation and the two-party method the same way, by having the
Use TaskManager to crawl 20 thousand proxy IP addresses for automatic voting. taskmanager2, 000
In other words, one day, I think of a whim. Some people in the circle of friends often send a voting link to help vote for XX. In the past, they would consciously open the link to help vote for XX. However, if we do more, we will consider whether we can use tools to vote. As a programmer, we decided to solve thi
