I would like to host my content on two different servers. There is the main website content domain.com/main-stuff, and there is the campaign pages content domain.com/landing-pages/other-stuff.

Is there a way for me to host these two things on different servers without using a subdomain?

I want to still show the users (and Google!) domain.com/landing-pages/other-stuff but that stuff would be hosted at lp.domain.com/other-stuff

Any guidance would be much appreciated.
