Hubspot Pages Use Different Domain


It’s was lightly touched on here: Subdomain vs Subdirectory - SEO and Rankings

I am looking to host a microsite on hubspot, using, but have it appear as I can configure this just fine via MaxCDN to proxy, but the issue is on Hubspot, there is no published way to set the domain in the source for links - we do not want our canonical tags pointing to . The only way I can see is running a reverse proxy with but we will not use Hubspot if it comes down to that.

Is there an undocumented way to pass along a header to Hubspot and have it use a different domain for it’s base_url? A lot of systems accept this functionality.
