I have 2 websites:
www.mysite.com
legacy.mysite.com
I want www.mysite.com/subfolderX to actually serve content from legacy.mysite.com/subfolderX. I don't even really need anything from legacy.mysite.com, and it won't be a publicly available URL, but rewriting the code to only handle what is in that one subfolder would be a pain.
Is there a way to do this with URL Rewrite, or do I need Application Request Routing?
