A modern Proxy Server does much more than forwarding web requests, all in the name of data security and network performance. Whereby a Proxy Server acts as a firewall and web filter. Providing a shared network connection, and cache data to speed up common requests.
A good Proxy Server keeps users and the internal network protected from the bad stuff that lives out in the wild internet. Lastly, proxy servers can provide a high level of privacy.
In computer networks, a Proxy server is a server that acts as an intermediary for requests from clients. Especially seeking resources from other servers. There are mainly two types of proxy servers. In that case, the two types include the forward proxy and the Reverse Proxy.
There is two main distinguishing difference between the Reverse Proxy and the Forward Proxy. On one hand, the forward proxy is used by the client such as a web browser. On the other hand, a reverse proxy is used by the server such as the general web server.
What is a Proxy Server?
A Proxy Server acts as a gateway between you and the internet. It’s an intermediary server separating end users from the websites they browse.
Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy.
If you’re using a proxy server, internet traffic flows through the proxy server on its way to the address you requested.
The request then comes back through that same proxy server (there are exceptions to this rule), and then the proxy server forwards the data received from the website to you.
If that’s all it does, why bother with a proxy server? Why not just go straight from the website and back?
Main common Types of Proxy Server in Use
Important to realize though that, the Forward Proxy Server can reside in the same internal network as the client.
Equally important too, it can also be on the Internet. Let’s have a major break down of the two server proxies.
1. Forward Proxy Server
Firstly, the Forward proxy can be used by the client to bypass firewall restrictions. Particularly, in order to visit websites that are blocked by schools, governments, companies, etc. And if a website blocked an IP range from visiting the website, then a person in that IP range can use a forward proxy. Above all to hide the real IP of the client so that person can visit the website. And maybe leave some spam comments.
However forward proxy might be detected by the website administrator. As a matter of fact, there is some paid proxy service that has numerous proxy systems. Especially around the world so that they can change your IP address every time you visit a new web page. Not to mention, this makes it harder for website administrators to detect.
Forward proxy was very useful and popular in the 1990s
Before NAT is integrated into network routers, the forward proxy is the way for multiple computers in the same network to access the Internet.
Furthermore, this type of forwarding proxy server usually resides in the internal network.
The forward proxy can also act like a cache server in an internal network
For your information, and in most cases, the forward proxy can also act like a cache server in an internal network.
With this in mind, if a resource is downloaded many times, then the proxy can cache the content on the server. So, next time when another computer downloads the same content, the proxy will send the content that is previously stored on the server to the computer. Moreover, there’re many different kinds of a forward proxy server. Such as;
- Web proxy,
- HTTP proxy,
- The SOCKS proxy, etc.
Please keep mind that using a forward proxy to browse the Internet usually slows down your overall Internet speed. That depends on the location between your computer and the forward proxy and how many people are using that forward proxy.
Another thing to be aware of is that there’re many free forward proxies which are built by hackers for malicious purpose. If you happen to be using one of these proxies, they will log every activity you do on the Internet.
HTTP and SOCKS Server Proxy Differences
In general, a SOCKS server is a general-purpose proxy server that establishes a TCP connection to another server on behalf of a client. And then routes all the traffic back and forth between the client and the server.
Further, it works for any kind of network protocol on any port. SOCKS Version 5 adds additional support for security and UDP.
A SOCKS server is a general-purpose server that establishes a TCP connection to another server on behalf of a client, then routes all the traffic back and forth between the client and the server. It works for any kind of network protocol on any port.
SOCKS Version 5 adds additional support for security and UDP. The SOCKS server does not interpret the network traffic between client and server in any way.
And is often used because clients are behind a firewall and are not permitted to establish TCP connections to servers outside the firewall. Unless they do it through the SOCKS server.
Most web browsers, for example, can be configured to talk to a web server via a SOCKS server. Because the client must first make a connection to the SOCKS server and tell it the host it wants to connect to, the client must be “SOCKS enabled.”
On Windows, it is possible to “shim” the TCP stack so that all client software is SOCKS enabled. A free SOCKS shim is available from Hummingbird at http://www.hummingbird.com/products/nc/socks/index.html.
An HTTP proxy is similar and may be used for the same purpose. When clients are behind a firewall and are prevented from making outgoing TCP connections to servers outside the firewall.
However, unlike the SOCKS server, an HTTP proxy does understand and interpret the network traffic that passes between the client and downstream server, namely the HTTP protocol.
Because of this, the HTTP proxy can ONLY be used to handle HTTP traffic, but it can be very smart about how it does it. In particular, it can recognize often repeated requests and cache the replies to improve performance.
Many ISPs use HTTP proxies regardless of how the browser is configured because they simply route all traffic on port 80 through the proxy server.
2. Reverse Proxy
A reverse is mainly used by server admins to achieve load balancing and high availability. A website may have several web servers behind the reverse proxy.
The reverse proxy server takes requests from the Internet and forwards these requests to one of the web servers.
Most visitors don’t know websites are using a reverse proxy. Simply, because they usually lack the knowledge and tools to detect it or they simply don’t care about it.
Nginx can be acting both a web server and a reverse proxy at the same time. HAProxy is another well-known open-source reverse proxy software.
Important to realize that; My IP Hide is better than Socks Proxy. Whereby, you’re allowed to hide IP address and unblock websites with lightning-fast, stable, and encrypted proxies.
