First of all, for end users, a transparent proxy can enhance their web browsing performance by caching frequently accessed web content, while introducing minimal configuration overhead for them. For administrators, it can be used to enforce various administrative policies such as content/URL/IP filtering, rate limiting, etc.</span></span></div> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1VrRyKPmaAN8_k1ni3Alq0RVqEPZim4tvw83TXom35GD6ZGJrboNOHhJ97rT251n4G6I7iWctMMqdO5wN9jm5mrF3yErWGe65h2lNz-DioH6G_eOWTR2IFdWRyI2pi9EiwY8B7F-8CN0J/s1600/squid-installation-hackthesec.co.in.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1VrRyKPmaAN8_k1ni3Alq0RVqEPZim4tvw83TXom35GD6ZGJrboNOHhJ97rT251n4G6I7iWctMMqdO5wN9jm5mrF3yErWGe65h2lNz-DioH6G_eOWTR2IFdWRyI2pi9EiwY8B7F-8CN0J/s1600/squid-installation-hackthesec.co.in.jpg" /></a></div> <div> <span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span></div> <div> <span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">A proxy server acts as an intermediary between a client and a destination server. The client sends requests to the proxy server which then evaluates the requests and takes necessary actions. In this tutorial, we will be setting up a web proxy server using Squid, which is a robust, customizable and stable proxy server. Personally, I had administered a Squid server with 400+ client workstations for about a year. Although I had to restart the service about once a month in average, CPU and storage utilization, throughput and client response time were all great.</span></span></div> <div> <span style="color: #0b5394;
