Why is "www.example.com” not the same as "example.com”?


I have a website. If I login in the domain of this format http://example.com and then change my address to http://www.example.com , i find my account is not logged in. If I change the address to http://example.com , I find my account is logged in.



I contacted my host, they told me its a programming issue.



How can i solve this issue so both addresses represent same access/session/cookies?



I'm using PHP & MySQL

div not scrolling properly with slimScroll plugin

I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth.

Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
