What does the second number in "POST / myfunction / HTTP / 1.1" 200 23 mean?

Question

I am trying to debug my django code in pycharm3,

I notice that when I run the request, I see the following in the launch window:

Django version 1.6.1, using settings 'driver1.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.
[19/Mar/2014 11:14:05] "POST /myfunction/ HTTP/1.1" 200 23

I know 200 is the HTTP status code for OK, but what is 23?

Answer 1

The second value describes the length in bytes of your response. Sometimes you will see the third value - this is the total time in seconds at which you answered.

So, your request /myfunction/responded to the HTTP status "OK", and the returned data was 23 bytes in length.
