Before making use of the available services like a proxy, one must understand and be clear about its advantages and how can it help the business.Before even looking into the benefits of proxy server it is also important to know what proxy is and how actually it works.
A proxy server is nothing but a server which will be between the user and the internet. In other words, it acts as a gateway between a large network and a local network. So, this is nothing but an intermediary server which will be between the internet and computer.
How does it work?
A proxy server sits in between server and client and acts as an intermediary. So, when the client requests for something, it goes via proxy to the actual server. So, the proxy browser will receive the request first and then it will work on behalf of the client.
When it receives the request, the first thing it does is it will look into its own cache. If the user has already requested for this page earlier, then it will easily find it in its cache and serves the request. In case if it is not able to find that request in the cache, it will go and request it to the respected server on behalf of the client.
In this case, since the proxy is making the request, the client’s IP address will not be in the picture. The proxy will make use of its own IP address. But in this entire process, there is no difference in the user’s experience. The user will feel like he is requesting for some web page and he received it.
There are many types of proxy servers. Some of them are
HTTP Proxy Servers
HTTP proxy servers help in interpreting the network traffic. So, they are in use for caching the web pages along with files. So, it will become very easy for users to access this whey they need them.
SSL Proxy Servers
These are also called as HTTPS proxies. These are the ones which offer SSL or secure socket layer. When the user makes use of SSL proxies, they are never get blocked by ISP.
SOCKS Proxy Servers
This doesn’t worry about the interpretation of web traffic like HTTP,but it just passes the request. These are the types of proxies which are very versatile,and they are capable of handling many types of traffic.
These are the proxies which can be placed inside the user browser. There is no need to install any other software to make use of these web proxies.
