How do you know that? Does your app freeze? (that would 
indicate the socket isn't writable). Nothing happens? (most 
likely the server is waiting for more - how does the server know 
when you're done sending?) Do you get an exception?

You're not checking how bytes were actually sent. I have no 
idea what createfilehandler does with the socket, although I'd 
guess that's not the problem.

There's a sockets HOWTO on python.org you should probably 
check out.

My first guess is that you haven't delimited the sent data 
properly, and the server is waiting for more.
