In computer networks, a reverse proxy or surrogate server is a proxy server that appears to any client to be an ordinary web server, but in reality merely acts as an intermediary that forwards the client's requests to one or more ordinary web servers. [1] [2] Reverse proxies help increase scalability, performance, resilience, and security, but ...
A reverse proxy (or surrogate) is a proxy server that appears to clients to be an ordinary server. Reverse proxies forward requests to one or more ordinary servers that handle the request. The response from the original server is returned as if it came directly from the proxy server, leaving the client with no knowledge of the original server.
Nginx (pronounced "engine x" / ˌ ɛ n dʒ ɪ n ˈ ɛ k s / EN-jin-EKS, stylized as NGINX or nginx) is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache.
Varnish (software) Varnish is a reverse caching proxy [2] used as HTTP accelerator for content-heavy dynamic web sites as well as APIs. In contrast to other web accelerators, such as Squid, which began life as a client-side cache, or Apache and nginx, which are primarily origin servers, Varnish was designed as an HTTP accelerator.
HAProxy is a free and open source software that provides a high availability load balancer and Proxy ( forward proxy, [2] reverse proxy) for TCP and HTTP -based applications that spreads requests across multiple servers. [3] It is written in C [4] and has a reputation for being fast and efficient (in terms of processor and memory usage).
Transparent' refers to the fact that the HTTP traffic is sent straight to the web application, therefore the WAF is transparent between the client and server. This is in contrast to reverse proxy, where the WAF acts as a proxy and the client’s traffic is sent directly to the WAF. The WAF then separately sends filtered traffic to web applications.
In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. It can, for example, allow private network communications to be sent across a public network (such as the Internet ), or for one network protocol to be carried over an incompatible network, through a process ...
A reverse connection is usually used to bypass firewall restrictions on open ports. [1] A firewall usually blocks incoming connections on closed ports, but does not block outgoing traffic. In a normal forward connection, a client connects to a server through the server's open port, but in the case of a reverse connection, the client opens the ...
