When we visit a website using our favorite browser, we usually just type in the basic part of the URL and ‘arrive’ at the desired location without any problems. But have we reached a point where we can start omitting ‘www’ from the URLs for all websites now, or is it still necessary to add it in?
Some places don't work with www at all: try typing www.localhost and see if you get looped back.
Name one website you have to type the www to get it to work (I have not seen any). Some sites will just redirect you to the www.domain if they use it, while others will accept www.domain or just domain. I personally never use the www
They are rare, but they do exist. Mostly due to older implementations of DNS registration. Most registrars automatically register the "non-www" version, as well.
I registered my site just yesterday, and while the prefix-less option was set by default, I COULD have removed it, causing this issue. Now, that would have been stupid (unless I fixed it on the server side, which had set up anyway), but it was an option if I cared.
I used to host on GoDaddy, and if I just typed my domain name in, it went to a GD landing page, and NOT to my web site. Kind of annoying.
You would have to adjust the settings for redirect for that.
All I'm saying is that www.domain.com and just domain.com are actually two distinct things. The fact that most web sites redirect one to the other is a convenience, and not a requirement. I typically don't bother with the www, either, but that does land me on error pages once in a while.
Regardless, I'm a lot more likely to get to a site through Google or a saved bookmark anyway, so it's not something I really think about.
