Question

I have oldsite.com which is redirecting to newsite.com. The site is run on Wordpress, NGINX and I am using wp supercache. I am having an issue where I am unable to get single page redirects working for html extensions. I have tried quite a solutions and nothing seems to be taking. so an example would be

oldsite.com/about.html redirects to -> newsite.com.about/

I have tried quite a few solutions with no luck. any help is appreciated. cheers

Answer 1

May be this is a solution to your answer. Please edit your .htaccess file and insert following code

  # Redirect to HTML if it exists.
  # e.g. example.com/foo will display the contents of example.com/foo.html
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME}.html -f
  RewriteRule ^(.+)$ $1.html [L,QSA]
