The Apache server project is a software development effort for creating a robust, commercial-grade, feature full and freely-available source code implementation of an HTTP server. The Apache server is available for various operating systems, but is most commonly used on operating systems such as Unix, Linux, and BSD.
After setting up an Apache web server or user account, you will see the generic Apache welcome page, similar to the picture to the right. If you see a page resembling this picture while browsing the Internet, the web page is experiencing issues or was recently setup. This page is to help indicate the server has been setup and is working and can be replaced with your website.
