.htaccess - Rewrite subdomain to folder in another domain -

i understand basics of .htaccess rewriting, next confuses me bit...

what want rewrite subdomain 'sub.domain.com' in way looks files of 'seconddomain.com/folder/'. without simple 301 redirect, want maintain showing url 'sub.domain.com'.

so 'sub.domain.com/file.html' should content of 'seconddomain.com/folder/file.html'.

who can help me right htaccess-rules? in advance.

(i assume can accomplished easiest .htaccess rewriting, if have improve solution same, allow me know!)

well tried, redirects , adds 'public_html' redirected url (so subdomain 'mijn.pingweb.nl' , folder redirect 'factuur.pingweb.nl/klanten/':
