REMOTE_ADDR = Your IP
Http_via = no value or no display
Http_x_forwarded_for = no value or no display
Second, the use of transparent proxy server situation: transparent proxies

A proxy is a common design pattern designed to provide a proxy for other objects to control access to an object. The proxy class is responsible for preprocessing messages for the delegate class, filtering messages and forwarding messages, and performing subsequent processing of the message after the class is executed.

JS method proxy and js proxy

As a scripting language, JS is very easy to use. With its flexibility, you can easily expand functions. Today, let's talk about the JS method proxy. Method proxy is a common method extension form in script language. This flexible form has the advantage that it can be e
Java Dynamic proxy ModeProxy: a role represents another role to implement some specific functions.For example, the relationship between producers, middlemen, and customersCustomers who buy products do not directly deal with producers, nor do they know how the products are produced. Customers only deal with middlemen, and middlemen can carry some packaging on the products, provide some after-sales services.
Proxy
In the java design mode, the proxy mode is widely used. For example, when I write a web program and modify the request or response in the filter, the request does not have a set method, in this way, you need to use a new class to implement the HttpServletRequest interface, put the original request into the new class and call the original method for the corresponding method in the new class. Then, the server passes the request to the Servlet so that th
The proxy mode provides an agent or placeholder for an object to control access to the object.

Forwarding can create a design that is very fragile and requires frequent maintenance.The load () method uses the JFrame object as a parameter to make a callback after the sp

Use Python to crawl available proxy IP addresses and python to crawl proxy ip addresses
Preface
Take the latest free proxy IP website as an example: http://www.xicidaili.com/nn /. Many IP addresses cannot be used.
So I wrote a script in Python, which can detect available proxy IP addresses.
The script is as follows:

SummaryArticleThis article describes how Castle's dynamic proxy implements AOP.
I have always been "tailism", that is, just use it, no matter how it is implemented. Recently, I have been paying close attention to AOP, Io C, and other technologies because I want to add them to the project. Later, dynamicproxy in the castleproject was selected as the object of interest. However, I was greedy this time and didn't wa
