I want to make it so that if a visitor navigates to:
http://www.website.com/folder
They get redirected to:
http://www.website.com/FOLDER
It is only for this specific folder that I want to affect (or intend to).
I have tried:
RewriteEngine On
RewriteBase /FOLDER/
RewriteRule ^folder(/.*)?$ /FOLDER$1 [L,R=301]
But I don't think that is right
In the htaccess file in your document root,
RewriteEngine On
RewriteRule ^folder(/.*)?$ /FOLDER$1 [L,R=301]
should be good enough. You don't need the rewrite base but I don't think that'll affect it.
