.htaccess - htaccess redirect page from subdomain to main domain -

i have problem redirecting page htaccess.

i've got page http://sub.example.com/mycontent , want redirect http://www.example.com/mycontent

i've tried make simple :

rewriterule http://sub.example.com/en/my-article http://www.example.com/en/my-article [l,r=301] 

but doesn't seems work @ all.

do did wrong ?

thank you.

you can't match host name in rewriterule.

you can use code in document_root/.htaccess file of sub domain:

rewriteengine on  rewritecond %{http_host} ^(?:www\.)?sub\.(example\.com)$ [nc] rewriterule ^en/my-article http://www.%1%{request_uri} [l,ne,r=302,nc]
