What do you need to do when buying a URL to point to a subpage, e.g. the url www.buythisproduct.com to point to

www.themainwebsite.com/buythisproduct

?

Yeah, it could indeed be a 301 redirect from the . Its a bit of a noob question from me and I'm not sure how else to explain it but basically I want to create a new page on a website and leaflets will be sent out with a more memorable URL e.g. www.cometothisurl.com and then the visitor will indeed be 301 redirected to the new page on the website.

Does performing a 301 redirect on the more memorable ULR require buying web space for it then purely for the 301 redirect? I was wondering if it would be possible to point the new URL at my new page without having to give that URL webspace.

Yep, to redirect to a sub folder you'll need to use htaccess, so you'll need hosting for the URL.

That can be done through your domain registrar. But you cant do that to a sub folder (i'm 99% sure about that, so check...).
