"""Simple HTTP Server With Upload based on python3.
Python2-Version by [bones7456] and [BUPTGuo]:
This module builds on BaseHTTPServer by implementing the standard GET and HEAD requests in a fairly straightforward manner.
Python3-Version by [FrozenMap]:
Based on the new features in python3, this module is built on [http.server] by rewriting some implementations of do_GET, do_HEAD and do_POST and other functions in Python2-Version.
20181029 Update:
With the help of [a.7], we can now upload multiple files together, rather than one file at a time
More details can be found on the blog with the link below:
https://jjayyyyyyy.github.io/2016/10/07/reWrite_SimpleHTTPServerWithUpload_with_python3.html
