The customer had an old non-wordpress site which had a folder called rsvp which did a redirect to a page in the old site.
In the new WordPress site, the equivalent location is this: http://rain1.com/new-site/customer-support/confirm-appointment/
So in the folder rsvp on the server I put this index.php
// redirect to new Rain1 WordPress site RSVP page
There is an htaccess page that (purposely) has this:
ErrorDocument 404 http://www.rain1.com/new-site
If I go to rain1.com/rsvp, I get the new site main page, NOT the desired page.
What is the correct way to do this?
