Firstly I would like to apologise for going a-wall postal on you all yesterday... and a big thanks to those who off list posted me to discuss last mile setups and what not, and generally giving me a helping knowledgeable hand :)
So heres my post for today:
Very frequently I trawl around and go to peoples websites (especially when I see an email on ausnog with a domain I haven't been to attached to it ;P )
I have done this again this morning and it got me thinking, how come a lot of people have these two cases:
A) I navigate to blah.com.au and is goes "can't connect to this server" I append www. to the domain (it ends up being www.blah.com.au) and I get their website.
B)The reverse of this, I navigate to www.blah.com.au and it says "Can't connect to server", but I go to blah.com.au and it is all cool.
What I am wondering is:
A) Why do people leave have these cases?
B) Where did the use of appending www. to the front of things originate from?
C) also I see sometimes www1. or www2. on some websites, can someone explain these to me?
Hope your all having a nice monday morning.
