Overview of this book

Squid Proxy Server enables you to cache your web content and return it quickly on subsequent requests. System administrators often struggle with delays and too much bandwidth being used, but Squid solves these problems by handling requests locally. By deploying Squid in accelerator mode, requests are handled faster than on normal web servers making your site perform quicker than everyone else's! Squid Proxy Server 3.1 Beginner's Guide will help you to install and configure Squid so that it is optimized to enhance the performance of your network. The Squid Proxy Server reduces the amount of effort that you will have to put in, saving your time to get the most out of your network. Whether you only run one site, or are in charge of a whole network, Squid is an invaluable tool that improves performance immeasurably. Caching and performance optimization usually requires a lot of work on the developer's part, but Squid does all that for you. This book will show you how to get the most out of Squid by customizing it for your network. You will learn about the different configuration options available and the transparent and accelerated modes that enable you to focus on particular areas of your network. Applying proxy servers to large networks can be a lot of work as you have to decide where to place restrictions and who should have access, but the straightforward examples in this book will guide you through step by step so that you will have a proxy server that covers all areas of your network by the time you finish the book.

Other log related features


We discussed important logging related directives in the previous sections. Squid has more directives related to logging, but they are less important and we should not have any problems in operating Squid normally, even if we are not aware of these features.

Cache store log

If we have disk caching enabled on our proxy server, Squid can log its entire disk caching related activities to a separate log file whose location is determined by the directive cache_store_log. This log file, contains information about the web objects being cached on the disk, stale objects being removed from the cache, and how long an object was in the cache. The information logged in this file is not particularly user-friendly. By default, logging of storage activity is disabled.
