This Sunday, I saw a piece of news which was written in 2009, but I think that many Internet users don’t know about its main idea.
...the address could have worked perfectly well without the two extra
unnecessary keystrokes.
Although it is a piece of old news, it is quite exciting to me. It is likely that some netizens who usually use a modern browser, which automatically fills up the type of protocol used on the left-hand side of the three ‘w’s in the input URL1, find this information useless. However, I sometimes need to specify the communication protocol in the URL (say, changing HTTP to HTTPS) for browsing some web contents.
