I added some code to my .htaccess , redirecting requests for a subfolder to the root domain, because there is a third-party site which is referring visitors to a subfolder which no longer exists (/MAU):
Rewriterule ^MAU(.*)$ http://www.mauivacationrental.com$1
Unexpectedly, this has disrupted access to an existing subfolder on my site, directing browsers to a default "non-existent URL" site. Here is the URL which is now broken:
Please advise how I can perform the redirect and avoid interfering with the valid link.
