You can do that by adding "print dir(request)" as the first line of the method. I'm sure you might find interesting information in there. Even if you don't, i can imagine you could maintain a list of "request" objects - global to that python module - and use that to communicate with all clients that have ever sent anything to the server. Hope it helps. Hi Nick,

I'm trying to have all connected users have access to one file, and when the file is updated, I'd like the server to notify all users of the update. This means I need that list!! haha thank you :) Do you know if there's any way to get a list of all websocket connections currently on the pywebsocket server?

Do a google search on hashlib and find the appropriate replacement calls for what is being done with the md5 library.
