lighttpd在proxy-core下path_info为空的修复

在lighttpd1.5以后，fastcgi module被抛弃，broken-scriptfilename参数也不存在了。我们只能在proxy-core里通过rewrite来设置path_info，类似配置如下：

$HTTP["url"] =~ "\.php" {

proxy-core.backends = ( "unix:/tmp/php-fastcgi.sock" )

proxy-core.protocol = "fastcgi"

proxy-core.allow-x-sendfile = "enable"

proxy-core.allow-x-rewrite = "enable"

proxy-core.rewrite-request = (

"_pathinfo" => ( "^/index.php/?(.*)" => "/$1" )

)

}
