How can I redirect to current d开发者_高级运维irectory with rewriterule. example: http://www.mySite/directory/subdirectory/index.php

now program is trying to goto vvv.mySite/index.php

RewriteEngine on 
RewriteBase / 
RewriteCond  %{REQUEST_FILENAME} !-d 
##RewriteRule . /index.php [L] 
RewriteRule . index.php [L]

Remove the RewriteBase directive so that the physical path is used.
