As a novice developer , you may not be exposed to proxy mode, but in many frameworks the use of proxy mode is unknowingly used, such as the servlet filter chain, Spring AOP, and Spring MVC Interceptor.

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

A reverse proxy (Reverse proxy) means that a proxy server accepts external connection requests and then forwards the request to a server on the internal network and returns the results obtained from the server to the external request-connected client. At this point, the proxy server behaves as a server.
