Squid has extensive access 44 controls and makes a great server accelerator. It runs on most available 45 operating systems, including Windows and is licensed under the GNU GPL. 46</p> 47 48<h3>Making the most of your Internet Connection</h3> 49<p> 50 Squid is used by hundreds of Internet Providers world-wide to provide their 51 users with the best possible web access. Squid optimises the data flow 52 between client and server to improve performance and caches frequently-used 53 content to save bandwidth. Squid can also route content requests to servers 54 in a wide variety of ways to build cache server hierarchies which optimise 55 network throughput. 56</p> 57 58<h3>Website Content Acceleration and Distribution</h3> 59<p> 60 Thousands of web-sites around the Internet use Squid to drastically increase 61 their content delivery. Squid can reduce your server load and improve 62 delivery speeds to clients. Squid can also be used to deliver content from 63 around the world - copying only the content being used, rather than 64 inefficiently copying everything. Finally, Squid's advanced content routing 65 configuration allows you to build content clusters to route and load balance 66 requests via a variety of web servers. 67</p> 68 69<p><q> 70 [The Squid systems] are currently running at a hit-rate of approximately 75%, 71 effectively quadrupling the capacity of the Apache servers behind them. This 72 is particularly noticeable when a large surge of traffic arrives directed to 73 a particular page via a web link from another site, as the caching efficiency 74 for that page will be nearly 100%. 75</q> - Wikimedia Deployment Information. 76<!-- ref: http://meta.wikimedia.org/wiki/Wikimedia_servers as of January 2009. --> 77</p> 78 79<h3>Want to learn more?</h3> 80<p> 81 The Squid project provides a number of resources to assist users design, 82 implement and support Squid installations.
