## httpd.py
#!/usr/bin/env python3

# so you want to write an HTTP server?
#
# 1. run `curl --trace-ascii http.log httpbin.org/html` and read http.log
# 2. run this code and try it in curl and your browser
# 3. good luck!
#
# here are some extra features to add:
#
# 1.  parse the request URI and serve up files from some directory
#     (so `curl localhost:1234/x/y` returns file y in dir x)
# 2.  refactor your code
# 3.  send Content-Length
# 4.  refactor your code
# 5.  implement threading
# 6.  refactor your code
# 7.  handle caching
# 8.  refactor your code
# 9.  handle large files (larger than your RAM)
# 10. refactor your code
# 11. get rid of threading and implement async I/O
