thats there total masala, but as i said before apart from the ctrl enter convenience..at some places...the site updation takes some time..but www. is pretty fast.
It doesn't matter from a PR standpoint really, just so that you pick one or the other. The only benefit of www is that when people type in an address they usually do www domain com and not domain.com. Although this seems to be changing with younger generations.
Not yet. I've asked at several forums and no one has given me any kind of answer. I've done a lot of web searches also for this and have found about 5 different variations of that code. They are pretty much all the same but all have minor differences like some will have a / at the end of the domain name and others a \ at the end. They are all different and I'd just like to know what the best code to use is so I dont screw something up by putting a bad code in.
