php - mod_rewrite domain to directory -


i want rewrite example.com url example.com/ru

for example if url example.com/books want have example.com/ru/books

i think can't header() function

this method incorrect 

<meta http-equiv="refresh" content="1; url=http://www.example.com/ru">

you should edit .htaccess redirect user queries @ / level new /ru/ level. should work purpose:

rewriteengine on rewritecond %{request_uri} !^/ru/ rewriterule ^(.*)$ /ru/$1 [l,r=301]

(both training , prediction can done in parallel, since problems assumed ...
