Yes it is possible, but why do you want to do that? You could use a 302 temporary redirect - but if its an estore there would be a lot of dynamic pages that could have links - I'm not sure how you could set that up to catch all those.
I have my e-store on the root directory of my domain.
I would like to now divert all trafic temporarily to say domain.com/blog instead of the root directory.
Is this possible?
