Alright this is a super weird request and it's just a stopgap measure until the client cleans up their many web properties, so no need to tell me that it's a convoluted way to do things. Current setup:
Question: Can I make the WP site at sub.example.com instead appear as example.com/sub? If so, how?
I can set the site_url and home_url in WP, and I can set up a forwarding rule from Squarespace to the IP of the GoDaddy shared hosting account. Would that be enough?
I had thought I would need to set an A record with the host as example.com/sub, but slashes aren't allowed. Any insight greatly appreciated. Thanks for reading!
the only way to get this done that I am aware, is to use some form of land balancer, e.g.:
last option will also speed up your site.
Unless your DNS provider have some custom option, DNS alone can't do that.
