apache rule with flag - QSA for lighttpd

Question

Apache HTTP Server

Help rewrite apache rule with flag - QSA for lighttpd.

Now available:

RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]

I'm trying something like this, but it doesn't work as it should:

url.rewrite-if-not-file = ( "^/(?:\?(.*))?" => "/index.php?_route_=$1" )

Answer 1

Thanks to all who sympathize, I figured it out:
Solution:
(url.rewrite-if-not-file = ("^([^\?]+)[\?]{0,1}(.*)$" => "/index.php?_route_=$1&$2")
