This allows the client to access the resources on the server. Proxy also handles the server and may provide additional features. Proxies are often used to improve performance, security and anonymity.

There are several types of proxies, including :

2. Reverse Proxies : These proxies act on the behalf of servers and receive request from the clients. They are used improve the performance by distributing the load among the multiple servers. They are providing the additional security by shielding the actual servers from direct access.

3. Transparent Proxies : These proxies are act as mediator between clients and servers. But it doesn't modify the requests and responses. They are often used to improve performance by caching content. 

4. Anonymous Proxies : These proxies act as mediator between clients and servers, but it doesn't reveal client's IP address to the server. They are mainly used to protect the privacy of user. 

5. Distorting Proxies : These proxies act as mediator between clients and servers, but modify the client IP address in the request. So that it is not traceable back to the original client. They are often used to protect the privacy of users.
