Exponential Performance Optimization Part 1 of 3: Introduction and Benchmarking

Website performance is one of the major factors that contribute to a good user experience. A slow website drives visitors away, while a responsive website encourages visitors to explore and contribute.

Using the Squid Reverse Proxy to Improve Exponential Performance

Squid is an Open Source proxy application that can also be used as a reverse proxy. The difference between a proxy and a reverse proxy is that a proxy delivers content from multiple webservers to one user, while a reverse proxy delivers content from one webserver to multiple users. For example, a normal proxy might be used to provide a degree of anonymity to a user or to access servers that would otherwise be blocked; the proxy would access many other servers on the user's behalf. On the other hand, one of the reasons for using a reverse proxy is to speed up the delivery of content to all visitors of a particular server. This article shows how to use Squid with Exponential to improve the performance of your website.
