    简介:这是一个 python 写的轻量级的文件共享服务器(基于内置的SimpleHTTPServer模块),
    支持文件上传下载,只要你安装了python(建议版本2.6~2.7,不支持3.x),
    然后去到想要共享的目录下,执行:
        python SimpleHTTPServerWithUpload.py
    或者 python SimpleHTTPServerWithUpload.py filename

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、基于 java netty 的 SimpleHTTPServer,

由于windows不支持某些 netty low-level API,该代码仅能运行在 linux 下:
