I dont quite understand what you mean.

I mean for example there is a site www.xyz.com and there is a subdomain abc.
So the link will go in this way of sub domain http://abc.xyz.com

My question is why its not necessary to place www infront of the subdomain

I hope m clear with the question..

Hi,

I'm not sure about it but generally people don't use 'www' before subdomains. I would also like to know if some one has knowledge about it.

I maybe wrong but dont they have something like a 7 day period in which you cannot push or is that only after receiving the domain name from a push?
