Dear Pavel,
thanks for your support. For whatever reason, when I copy the javascript
code directly into the HTML file, web sockets do work. If I put the code in
a separate .js-File, web sockets do not work. I think I will go with it
having the web socket code within the HTML document.
Regards
Bjoern

connections
Can you please share your application and steps you are doing? I cannot
reproduce described behavior with our (simplelife) sample.
Other than that - most browsers provide some kind of debugging support -
intercepting HTTP headers should be present in all major ones, so you might
want to check whether the response was received and if so, then its status
and headers. Or you can try something like
tcpdump -i lo -n -nnvvXSs 1514 port 8080
(requires root)
Sending the sample would still be useful, I will at least try it out and
check whether it is working in my environment or not.
Thanks,
Pavel
