In this article, we are going to see the list of Best Reverse Proxy in 2018. We will start off with what is a reverse proxy to how does a reverse proxy work and then we will list a bunch of reverse proxy for you to set up for your website.
What is Reverse Proxy
A forward proxy or a normal proxy is an intermediary for the client that wants to request the server. While a reverse proxy is an intermediary for the server that wants to respond to the client. Thus reverse proxy will hide the characteristics and the nature of the origin server. Reverse proxy will offload the incoming traffic to several another server which server having its own application area. Reverse proxy essentially caches the static and dynamic content (also known as web acceleration) and speed up the website by a very significant margin.
How does a Reverse Proxy work:
A reverse proxy is a proxy server that is behind the firewall of the private network and directs the client request to the appropriate backend server. Since the reverse proxy is behind the firewall of the private network, it receives only the requests that pass the firewall rules and then forwards the request to the appropriate backend servers. They are also, capable of caching the inbound and outbound data and server them in order to remove the load from the main server. This process is called web acceleration.
Now that we have seen the basics of how a reverse proxy works and also what is a reverse proxy, we can see some of the best reverse proxy listed below.
Nginx is not just a reverse proxy. It has a full web server, reverse proxy etc. Nginx application platform powers load balancers, microservices and API Gateways. A large portion of the web servers uses Enginx. Enginx was specifically designed to serve a large number of concurrent clients.
Considering only the Reverse Proxy feature of Enginx we can see that, When Enginx proxies a request it sends the request to a specific proxy server and fetches the request and sends it back to the client. By default Nginx buffers responses from the proxy server. A response is stored in the internal buffer and is not sent until the whole response is received. To enable compression to include the gzip directive on the parameter.
Apart from that, we can check out the features offered by the Nginx as below:
- It serves dynamic HTTP content.
- Uses FastCGI, SCGI, and WSGI.
- It acts as a load balancer.
Varnish is a very popular and powerful HTTP engine and Reverse HTTP proxy. It can speed up the website by 1000 percent by doing exactly what it says that is caching. Speed and performance have made varnish so powerful and popular. It helps save lots of server infrastructure.
Check out the following major feature of Varnish Cache:
- Varnish helps the server meet the demand no matter the number of client requests.
- If the server fails, it continues to serve the cached content, thus enabling protection against server outage.
- Varnish configuration language builds a customized solution, rules, and modules.
Unlike Nginx, Varnish is only a caching web accelerator that speeds up your website.
Squid Caching is a proxy for the web that supports HTTP, HTTPS, and FTP. It reduces the bandwidth and improves the response by caching. Squid’s advanced content routing configuration allows you to build content clusters to route and load balance request using a variety of web servers.
Some of the important features of Squid are:
- Squid is used by thousands of internet providers around the world.
- Squid caches frequently used content to provide improved performance.
- It can build cache server hierarchies which optimize network throughput.
HA Proxy is free and varies fast solution for proxying TCP and HTTP based application.
The following are the features of Ha proxy:
- Native SSL support.
- It supports HTTP/1.1 compression
- Client-side keep alive to reduce the time to load heavy pages.
- Response buffering to reduce the number of concurrent connection to the server.
- Server management through the CLI to avoid restarting the server to enable changes etc.
In this post, we saw what is a reverse proxy, how a reverse proxy works, and some of the best reverse proxy software that you can get in 2018 and further. For more detailed content on Reverse proxy, VPNs, Computer tips and tricks, please stay tuned to My Pc Updates.
