reverse proxy configuration

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 length is 0 or equal to "unknown", then:IP = request.getheader ("Wl-proxy-client-ip")4) If

Nginx default configuration file is not in the log forwarding configuration, this requires our own manual to operate, and then the end of real server different operating methods are not the same, here we give a few examples to illustrate. Nginx do front-end, forward log to back-end Nginx server: Because the needs of the architecture of multi-level Nginx reverse

can be accessed across the domain of the vulnerability or skill to complete, but all the target server to make the corresponding changes, and I recently encountered a demand is that The target server can not give me a header, but also can not change the code to return a script, so the first 5 kinds of programs are rejected by me. Finally because my website is my own host, so I decided to build a nginx and put the corresponding code under it, by the page request an address of the domain name, th

Problem Background In the practical application, we may need to obtain the user's IP address, for example makes the remote landing the judgment, or the statistics IP accesses the frequency and so on, usually we use the request. Remoteaddr can get to the client IP, but when we use the Nginx as a reverse proxy, use request. Remoteaddr gets the IP address of the Nginx server, then what should be done. principl

Squid is a very popular server software under a UNIX-like system, and its most important function is to establish a cache between the client and the service. So squid can be used as a reverse proxy, deploy multilevel caches or build CDNs, whatever the name is, essentially the same. Currently there is also a ported version of Squid in Windows that can be used for scenarios that use Windows environments. Here

As mentioned earlier, using a proxy server can forward requests to an internal Web server, and using this acceleration pattern can obviously improve the access speed of static Web pages. However, it is also possible to consider a technique that uses a proxy server to forward requests evenly to multiple Web servers to achieve load balancing purposes. A member of the Apache Development Group Ralf S.engelscha

Nginx reverse proxy is a common function of the process of Web layout. After setting the reverse proxy, by reading the HTTP header inside the REMOTE_ADDR can not get the true user IP, we need to increase the nginx configuration to solve this problem. The following is an exp

Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load balancer and execute
