I have already wrote a post almost a year back about Proxy servers. I am again writing about it but this time in detail. It will be a chain of articles in which i describe proxy servers and all the types of proxy servers.
In general, people think that proxy servers are those which are used to hide our IP adress in order to be anonymous on the internet. But anonimity is only a use of proxy servers. Read the full post to know what actaully the Proxy Server is?
Proxy server: Proxy server is the server system which acts as the intermediate between client and server systems. When a client want to connect to a server using proxy, client's system first connect to the proxy server, and proxy then connent client's request with the server system. In this way, client have an indirect connection with the target server system. But proxy do not have only the work of connecting client and server. It provide various service at the network level to improve the connectivity and and performance. It is mainly used for performance improvements and packat filtering
Every proxy server have some set of rules and the requests of the clients are evaluates based on those set of rules. If your college has blocked the facebook, twitter, youtube and some other websites, it means the proxy server of your college do not have some set of rules which block the requests to these websites. So it filters all the packets which request for the connection with these websites.
Proxy server also perform caching service so it can also serve some request without contacting with the original server. Thus it can improve the performance.
How it Provide anonymity: As i have described above that Proxy server connects your system to the server indirectly. So the server knows only about the proxy not about you because you have no direct connection. Thus you are anonymous.
Advantages of Proxy servers: These are some advantages of the Proxy servers on the network.
- · Proxy servers provide anonymity on the internet due to indirect connection between users and servers.
- · It is used to scan the packets going outside and inside the networks. So it can used to determine the data leakage and data theft.
- · Proxy servers can also be used to block some websites on the network.
- · It can provide some features of Intrusion Detection system and Firewall
- · Firewall can also logs data usage of each user on the internet.
Types of Proxy servers:
- · Caching Proxy Server
- · Web Proxy Server
- · Content Filtering Proxy Server
- · Anonymizing Proxy Server
- · Hostile Proxy Server
- · Transparent Proxy Server
- · Reverse Proxy Server
I will write about these type of proxy servers in detail incoming artiles. Stay tuned and subscribe for lates updates.
Would love to here from you...
