My aim is:
domain.com/folder
rewrite ->
domain.com
this shall concern ALL links inside that site. I mean
You can use this code:
Goes in DOCUMENT_ROOT/wedgiecommunity/.htaccess:
RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+wedgiecommunity([^\s]*) [NC]
RewriteRule ^ %1 [R=301,L]
Goes in DOCUMENT_ROOT/.htaccess:
RewriteEngine On
RewriteRule !^/?wedgiecommunity wedgiecommunity%{REQUEST_URI} [L,NC]
You can use this rule to "remove" the folder from the URL when it is accessed directly via the browser:
RewriteCond %{THE_REQUEST} \ /wedgiecommunity/
RewriteRule ^wedgiecommunity/(.*)$ /$1 [L,R=301]
Then your other rule will handle the rest.
