Multiple domains pointing to 1

[Alex Locklear]

I'm wanting to target multiple cities/markets and want to create multiple domain names/websites that all forward to my main site (so I don’t really have to create a new site for each domain).

Does anyone know the best way to do this? I know there is masking/forwarding/different ways to potentially do this but want to know the best way and don’t want to negatively effect my site somehow.

Thanks in advance!
