The document outlines a series of laboratory exercises for configuring and using the Apache web server. It includes instructions for: 1) Setting up virtual machines and configuring network settings to host Apache websites. 2) Installing and testing Apache, and familiarizing with its configuration file. 3) Configuring Apache as a secure reverse proxy and implementing basic security restrictions. 4) Enabling user-based authentication and using .htaccess files to set authorization at subdirectory levels. 5) Configuring virtual hosting with a single or multiple IP addresses to host multiple websites from one server. 6) Enabling SSL/TLS using self-signed or real certificates signed by a Certificate Authority.
