title: How do I mask a subdirectory of one URL to a subdirectory of a different URL?
body: <p>I have a VPS running Linux and Wordpress with multiple domains.</p>
  
  <p>I want people to be able to go to B.com/b1, and see the page at A.com/b1, but without the URL changing (the URL will still show B.com/b1). However, I don't want it to mask the entire domain- just those subdirectories on each domain.</p>
  
  <p>I will then need to do the same thing with C.com/c1 (using A.com/c1 page), D.com/d1 (using A.com/d1 page), etc.</p>
  
  <p>I <em>think</em> this can be done with htaccess page, but that's the extent of my knowledge. I searched, but didn't see this answered specifically. I really appreciate the help!</p>
