Simple htaccess redirect - subdomain to folder

Question

I am trying to redirect http://[random-string].domain.com/ to http://domain.com/folder/[random-string]/

I currently have this:

RewriteCond %{HTTP_HOST} ^.*\.domain\.com
RewriteRule ^.*$ http://domain.com/folder/$1/ [R=301,L]

It currently points to http://domain.com/folder//. (The $1 is missing) How do I fix this?

You need to use parenthesis to grab the value matched, in your case:

RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ http://domain.com/folder/%1/$1 [R=301,L]

assuming you also want to redirect http://[random-string].domain.com/something to http://domain.com/folder/[random-string]/something
