Hi there,

So sorry for this late reply but I was away. You're right, it's a bug and I just fixed it.

Thanks for this.

Hello,

I want to use ws4py as the link between a javascript web app and a python daemon.

I'm using the stock wsgirefserver, and this html:
<html>
<head>

<script>
var socket = new WebSocket('ws://localhost:9000/');
</script>

</head>
</html>

On connection, an assertion error gets thrown:
Traceback (most recent call last):
File "/usr/lib/python2.7/wsgiref/handlers.py", line 85, in run
self.result = application(self.environ, self.start_response)

File "/home/plg/documents/websocks/ws4py/server/wsgiutils.py", line 153, in __call__
start_response("101 Switching Protocols", upgrade_headers)
File "/usr/lib/python2.7/wsgiref/handlers.py", line 178, in start_response

assert type(val) is StringType,"Header values must be strings"
AssertionError: Header values must be strings

Is this normal?
