About this tutorial

Welcome to "Web services," the fourth of seven tutorials covering intermediate network administration on Linux. In this tutorial, you learn how to configure and run the Apache HTTP server and the Squid Web Proxy Cache.

As with the other tutorials in the developerWorks 201 and 202 series, this tutorial is intended to serve as a study guide and entry point for exam preparation, rather than complete documentation on the subject. Readers are encouraged to consult LPI's detailed objectives list and to supplement the information provided here with other material as needed.

This tutorial is organized according to the LPI objectives for this topic. Very roughly, expect more questions on the exam for objectives with higher weight.
