if (!-e $request_filename) {

is this equivalent?

I created a blog named test with the above rules, with http://blogs.domain.com/test/ I get a Bad Request response (Your browser sent a request that this server could not understand.) from apache
([Tue Dec 01 22:22:11 2009] [error] [client 127.0.0.1] Invalid URI in request GET index.php HTTP/1.0
apache error_log)

http://blogs.domain.com/test/ only match with "rewrite ^. index.php last;" not? then... I do not understand how it works in nginx apache and not with those rules

thanks!
