Hi, I wish to host some files in a way that they are accessible through a net browser. Like this picture shows:

I have now tried to set up apache2 with webdav, however I don't get to browse any files. If I enter the IP-adress of my server, a message saying "It works!" shows up. What should I do in order to host files?

PS: I have followed this tutorial:
