My Question is this:
I have a primary domain (assume it's domain.com).
Now I parked domain-static.com on domain.com.
The idea is that static content (images, JS, CSS) is served from domain-static.com,
and domain-static.com passes through a CDN which is where the difference is between the domains. The reason is that browsers limit simultaneous downloads from the same domain so I think it should speed up the site more than routing all requests through a CDN.
The static domain is actually parked on top of domain.com, but all static content on the website is served through static-domain.com
There shouldn't be a case where HTML pages are served from domain-static.com or really for anything Google downloads (except for images which it will download for Google Images)
But I'm asking about the regular Google search, can domain.com get penalized for some reason for parking domain-static.com on domain.com?
If this is so, one possibility I thought of is adding an .htaccess rule that doesn't let any dynamic content be served from the static domain, so there isn't a possibility of Google downloading dynamic content from the domain-static.com, which can eliminate dynamic content.
What do you think I should do?
