我有以下lighttpd重定向规则，需要将它们转换为nginx：
url.rewrite-once = (
"^/misc(.*)" => "/misc$1",
"^/show_fileupload.php(.*)" => "/show_fileupload.php$1",
"^/flash(.*)" => "/flash$1",
"^/images(.*)" => "/images$1",
"^/css(.*)" => "/css$1",
"^/js(.*)" => "/js$1",
"^/filestore(.*)" => "/filestore$1",
"/(([a-f0-9]{32})/)?(app/(.+?)/)(lang/(\w{2}-\w{2}|\w{2}|)/)?/*([^\?]*)(?:\?(.*))?" => "/$4.php?rs_module_uri=$7&rs_session=$2&rs_app=$4&rs_lang=$6&$8",
"/(([a-f0-9]{32})/)?(app//)?(lang/(\w{2}-\w{2}|\w{2}|)/)?/*([^\?]*)(?:\?(.*))?" => "/main.php?rs_module_uri=$6&rs_session=$2&&rs_lang=$5&$7",
)
如何转换特别是最后两行？
