1、httpserver
=======================================
This httpserver is a enhanced version of SimpleHTTPServer.
It was write in python, I use some code from bottle[https://github.com/defnull/bottle]
It support resuming download, you can set the document root, it has more
friendly error hit, and it can handle mimetype gracefully
https://github.com/lerry/httpserver/blob/master/httpserver.py
2、基於 java netty 的 SimpleHTTPServer，
由於windows不支持某些 netty low-level API，該代碼僅能運行在 linux 下：
