.htaccess redirects without extension in url - .htaccess

Question

I'm hiding my file extensions with
RewriteEngine On
# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ http://example.com/folder/$1 [R=301,L]
# Redirect external .php requests to extensionless url
RewriteCond %{THE_REQUEST} ^(.+)\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^(.+)\.php$ http://example.com/folder/$1 [R=301,L]
# Resolve .php file for extensionless php urls
RewriteRule ^([^/.]+)$ $1.php [L]
When I navigate to this link
http://localhost/website/profile?user=user01&nofollow=1
I'm redirected here
http://example.com/folder/profile?user=user01
I've taken .php out of the url. Why does it redirect me?

Answer 1

Have it this way inside /website/.htaccess:
RewriteEngine On
RewriteBase /website/
# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ $1 [R=301,L]
# Redirect external .php requests to extensionless url
RewriteCond %{THE_REQUEST} ^(.+)\.php[?\s] [NC]
RewriteRule ^(.+)\.php$ $1 [R=301,L,NC]
# Resolve .php file for extension-less php urls
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^([^/.]+)$ $1.php [L]
Make sure to clear your browser cache before testing this.

Try using this:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{REQUEST_METHOD} !POST
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=302,L,NE]
## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME}.php -f [NC]
RewriteRule ^ %{REQUEST_URI}.php [L]
