Proxy Server Operation

We use Proxy server for restrict the access of some web sides. The function of the Proxy server is blocking the web site. 

Proxy server operation

 

We type the address according to the OSI model before adding frame, we put destination IP address as 100.10.11.48, add frame and transmit frame to the destination (ABC   Server IP 100.10.11.48).This frame is going through the proxy server. Proxy server checks the destination IP address and if it restricts the web side by the network administrator, server blocks the Frame. That is the process of Proxy web server.
