Lighttpd sitemap problem

Hello guys!
I get 404 when trying to test my sitemap file. I have typed in the rewrite rule in the config file. Here is a part of it.

server.modules = (
"mod_rewrite",
# "mod_redirect",
"mod_alias",
"mod_access",
"mod_auth",
"mod_status",
# "mod_setenv",
"mod_fastcgi",
# "mod_proxy",
# "mod_simple_vhost",
# "mod_evhost",
# "mod_userdir",
# "mod_cgi",
# "mod_compress",
# "mod_ssi",
# "mod_usertrack",
# "mod_expire",
# "mod_secdownload",
# "mod_rrdtool",
"mod_accesslog"
)


And the rewrite rule.

url.rewrite-once = ( "^/(sitemap.*\.(xml|txt)(\.gz)?)" => "/vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1" )

What can i be doing wrong?

Hello,

can you get any other rewrite rule working for testing? (to make sure that rewrite module works correctly)
