reverse-proxy

问题 These are two phrases I hear about very often, mainly associated with Nginx. Can someone give me a laymans defintion? 回答1: Definitions are often difficult to understand. I guess you just need some explanation for their use case. A short explanation is: load balancing is one of the functionalities of reverse proxy, and reverse proxy is one of the softwares that can do load balancing. And a long explanation is given below. For example a service of your company has customers in UK and German.

问题 In my project, web app is developed using Spring boot with default tomcat server. I am using NGINX as load-balancer and have configured my spring-boot-web-app in NGINX configuration as follows: location /spring-boot-web-app { proxy_pass http://spring-boot-web-app/ } http { upstream /spring-boot-web-app { server <IP_of_spring_boot_app>:<Port_of_spring_boot_app> } } Now lets say NGINX IP and port as nginx_ip and nginx_port respectively. Also working URL for my web app as: http://web_app_ip:web

问题 I am running a Jetty-based Web Service behind an NGINX reverse proxy. Both Jetty and NGINX can handle the gzip compression/decompression for responses and requests. The typical payload is JSON, ranging from a few kilobytes up to tens of megabytes. Especially for larger payloads, the compression significantly impacts overall throughput. What would be the most efficient point to handle the compression part - the JAVA service (Jetty) or the proxy (NGINX) if both sit on the same server? Since

问题 I have a server running at http://localhost:8080 i want a specific url of this server to be proxied by nginx. For example, i only want http://localhost:8080/test/(.*) to be reverse proxied to http://localhost/test/(.*) . I'm proxing another server to http://localhost/ . 回答1: What about just a simple location block? server { # ... other stuff location /test/ { try_files $uri @testproxy; } location @testproxy { proxy_pass http://127.0.0.1:8080; proxy_set_header X-Forwarded-Host $server_name;

问题 I checked the cache path /usr/local/nginx/proxy_cache. No cache file found after I visit some url many times. My configuration: ngnix.conf http { include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; client_body_buffer_size 512k; proxy_temp_file_write_size 128k; proxy_temp_path /usr/local/nginx/proxy_temp; proxy_cache_path /usr/local/nginx/proxy_cache

问题 I have a page at host1.mydomain.com/page_from_host1.jsp and an HTML page at host2.mydomain.com/page_from_host2.html. host1 is an IIS7/Tomcat box and host2 is an IIS7 box. I want to allow the first page to submit a form, which displays the second page, and the URL does not change. That is, the URL is host1.mydomain.com/page_rom_host2.jsp, but the contents of the page are from host2.mydomain.com/page_from_host2.html. I would imagine I can setup a reverse proxy on IIS to accomplish this, similar

问题 For the life of me, I couldn't get mod_remoteip to get client IPs in my Apache access logs. I'm working on a Virtualmin setup with Varnish 4 installed in front of Apache 2.4.7. How do you get it working? 回答1: I finally got the client IPs in the log and I found the last step here: Here are the steps to getting it to work: Get Varnish to pass a header to Apache with the client IP. You do this by including this bit of code (found in this answer) at the very beginning of your vcl_recv: if (req

问题 What is the most accurate way to get user's IP address in 2017 via PHP? I've read a lot of SO questions and answers about it, but most of answers are old and commented by users that these ways are unsafe. For example, take a look at this question (2011): How to get the client IP address in PHP? Tim Kennedy's answer contains a recommendation to use something like: if (!empty($_SERVER['HTTP_CLIENT_IP'])) { $ip = $_SERVER['HTTP_CLIENT_IP']; } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
