proxy server ip

In the development work, we often need to obtain the client's IP. The general method to obtain the IP address of the client is: Request.getremoteaddr (), but the real IP address of the client cannot be obtained by the reverse proxy software such as Apache,squid.Cause: Because the intermediary agent is added between the

Preface: Today to explain to colleagues the proxy server and reverse proxy server, draw a picture to explain.Proxy servers typically fall into two categories, the forwarding agent (forward proxy) server and the reverse

20120917@ Zheng yu Summary The common Java/PHP server obtains the Client IP address as follows: PseudoCode: 1) IP = request. getheader ("X-FORWARDED-FOR") Forge. See Appendix. 2) If the value is null or the array length is 0 or equal"Unknown", Then: IP = request. getheader ("

One, manually update the IP pool method One: 1. Add the IP pool in the settings profile: ippool=[ {"ipaddr": "61.129.70.131:8080"}, {"ipaddr": "61.152.81.193:9100"}, {"ipaddr": " 120.204.85.29:3128 "}, {" ipaddr ":" 219.228.126.86:8123 "}, {" ipaddr ":" 61.152.81.193:9100 "}, {" IPAddr " : "218.82.33.225:53853"}, {"ipaddr": "223.167.190.17:42789"} ] These

access the same page, or the same account for a short period of time to do the same operation. Most sites are the former, and in this case, IP proxies can be used to solve them. We can save agent IP detection in the file, but this method is not desirable, the possibility of proxy IP failure is very high, so from the

First, do not use the proxy server situation: 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 REMOTE_ADDR =
