Is the Web server bound to listen only to the localhost?
If you bind the apache web server to the local interface, so that it isn't accessible to other machines, it can still serve up pages to browsers/web clients on this machine. This is ideal for many web developers, who don't need a worldwide accessible web server, but would like to edit a web site locally before uploading to another server. To access the server, you would simply use, as a URL in your browser: http://localhost/ and http://localhost/some_page.html Even if you fully deactivated the web server in the previous step, this option still makes sense: if you or someone else turns the server back on, it doesn't represent as great a risk if it isn't set to allow connections from the entire internet.
