Your HTTP in the client
If you have a browser and/or terminal, you don't need additional things.
When you install your server configuration can check this
With browser
HTTP Simple (http://www1.st.um)
HTTP Simple with authentication (http://www2.st.um)
HTTP with SSL (https://www3.st.um)
With terminal
With the browser url access is sufficient, but you need feel like a hacker, you can do the same but in terminal
