Question

How to get file directory trough .htaccess by using RewriteRule ^(.*)$ ?id=$1 [L,QSA]?

If .htaccess is located in http://localhost/some/dir/.htaccess and I'm opening http://localhost/some/dir/here/I/use/RewriteRule/, how I detect value /some/dir/ without using RewriteBase and without manual adding %{DOCUMENT_ROOT}/some/dir/, like value localhost I get trough %{HTTP_HOST}?

Answer 1

mod_rewrite does not know what portion of the URL got it to a specific directory, which is why RewriteBase is needed to generate proper links for relative substitutions in all but the simplest case.

You have to bake this info into your ruleset.
