Redirecting the url entered with htaccess to a different location in the same way

Question

When I enter my example.com url I want to redirect to example.com/en/ but when I enter example.com/demo I want to redirect to example.com/us/demo. The word demo here is just variable. how can I do that ?

My .htaccess code:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /tr/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /tr/index.php [L]
</IfModule>

Try the following before your existing directives (ie. before the <IfModule> section):

# Redirect "/" to "/en/"
RewriteRule ^$ /en/ [R,L]

# Redirect "/demo" to "/us/demo"
RewriteCond %{REQUEST_URI} !^/(en|us)/
RewriteRule (.*) /us/$1 [R,L]

The first rule redirects example.com/ to example.comn/en/. The second rule redirects everything else to /us/<url>, providing the URL-path does not already start /en/ or /us/.

If you also need to make an exception for your static assets... eg. Should a request for /assets/images/img.png also be redirected? Then include an additional condition (as the 2nd condition) on the second rule:

# Redirect "/demo" to "/us/demo" (and exclude static assets)
RewriteCond %{REQUEST_URI} !^/(en|us)/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) /us/$1 [R,L]

Note that these are 302 (temporary) redirects.
