Python Demo Socket Servers

Once a colleague asked me how to peep what headers a browser sends to a server. I suggested to write a minimal server that would store a request to a file.

Then I realized that the task would be really interesting to implement. I can learn how to use SocketServer or BaseHTTPServer library. So I wrote it myself.

The results are here. To learn sockets and socket servers better I implemented 4 different servers:

• get_request.py - simple socket server. It is not HTTP server, so it cannot recognize the end of HTTP request. If a browser after sending request does not close the connection (Connection: keep-alive) you need to press Esc in browser to close the connection and allow the server to log the request.
• get_http_request1.py - simple HTTP server using pure sockets.
• get_http_request2.py - simple HTTP server using SocketServer.
• get_http_request3.py - simple HTTP server using BaseHTTPServer. It implements GET, HEAD and POST request.

You can download them at once: get_request.tar.bz2.
