Pointing a sub-domain to a sub-folder in htaccess

[acs111]

I have a client who currently uses shopify for there blog. I want to set them up with a separate blog away from the shopify system and host it in Australia.

I know the best option is using a subfolder but as the shopify system is an unmoveable CMS can I somehow point my subdomain to a subfolder and get the benefits of the domain name?

I could do this by using the rewrite rule in the htaccess file.

If I was to do this would it end up cloaking the URL's of the articles?

Well, in that case, I don't think you will be able to set it up as domain/blog. Using a subdomain is likely your only option, blog.domain.

But, I wouldn't worry too much about it since Google doesn't really treat the two situations much differently. Matt Cutts recently commented on this exact situation:

So, I'd go ahead and set up your blog at your secondary host, and point your subdomain to it.

Yes. the blog would be set up on am Aussie host.

It is a custom domain

Are you saying that:

1. Your client has an ecommerce site that uses shopify.

2. You want to set up a blog for their site, on a separate host.

3. But you'd like it to appear as if it were a subfolder of the main site (e.g. mysite.com/blog), rather than a subdomain (blog.mysite.com)?

Is that correct?

And, is the domain a custom domain that points to shopify?
