When you have a high traffic website it could be hard to handle the huge amount of traffic. Of course, there are many ways to deal with your increasing traffic like purchasing more hardware, but why spend more money when you could get the most out of your Ubuntu server with just a little effort?
If you are looking for a way to spend less you could use a web cache proxy like Squid. This is an open source caching proxy for the Web supporting HTTP, HTTPS, FTP that reduces bandwidth. Squid also improves the response times by caching and reusing frequently-requested web pages. For example, if your visitor already opened a file on your website, the next time he opens the same file will be much faster due to the infrastructure of the proxy. So it definitely offers a rich set of traffic optimization options, most of which are enabled by default for simpler installation and high performance.
– Squid enables you to deliver content from around the world, not everything will be copied but only the content that is being used.
– You can control traffic for malicious content and remove it.
– You can run Squid on many operating systems including Windows.
