If it's HTTP validation, send a request to the proxy to see if there is a response! HttpWebRequest objHttpRequest; HttpWebResponse objResponse; WebProxy objProxy;

objHttpRequest=(HttpWebRequest)WebRequest.Create(m_strUrl); objHttpRequest.Timeout=3000; objHttpRequest.AllowAutoRedirect=true; objHttpRequest.ContentType="application/x-www-form-Urlencoded";

objProxy=new WebProxy(ProxyName,PortID); objProxy.BypassProxyOnLocal=true; objProxy.Credentials=new NetworkCredential(UserID,Pwd,Domain);

objHttpRequest.Proxy=objProxy; try { objResponse=(HttpWebResponse)objHttpRequest.GetResponse(); } catch(Exception e) { throw e; } The use of HTTP proxy IP can be used for browsers to visit web pages, send HTTP requests, commonly used for web crawlers, web voting, website registration, etc.; The IP is dynamically updated, and when the server makes a new request, it gets a new IP address. However, not all services are suitable for dynamic IP, such as sending multiple requests or visiting multiple web pages, it is recommended to use the same IP.

As we all know, HTTPS is suitable for securing the connection between the browser and the website. If you use a public WiFi hotspot and the website does not use HTTPS, then many WiFi hackers and hotspots can monitor your behavior and traces on the website through the the network.

Many shopping malls and restaurants in China now have many public hotspots, and now free public hotspots are usually the behavior of commercial enterprises. Where to buy an agent? That's a good question. Where to buy a safe and reliable agent?

Are you already thinking about your cyber security? Are you concerned about your privacy being sold? Then use a proxy IP can prevent this from happening.
