Suppose my external process is registered and has a name, so I can +discover it by name from my cowboy request handler. when my cowboy handler +is invoked, can I just send the handler's process ID to the external +process? the question is then how does the external process know that the +http client has disconnected so that it can stop sending data to it. + + +2013/9/16 Loïc Hoguin <<A HREF="https://lists.ninenines.eu/listinfo/extend">essen at ninenines.eu</A>> + +><i> On 09/16/2013 03:50 PM, akonsu wrote: +</I>><i> +</I>>><i> Hello, +</I>>><i> +</I>>><i> this is somewhat similar to what someone else has asked: +</I>>><i> <A HREF="http://lists.ninenines.eu:81/**archives/extend/2013-August/**000224.html<http://lists.ninenines.eu:81/archives/extend/2013-August/000224.html">http://lists.ninenines.eu:81/**archives/extend/2013-August/**000224.html<http://lists.ninenines.eu:81/archives/extend/2013-August/000224.html</A>> +</I>>><i> +</I>>><i> I am new to cowboy, I have a process that runs alongside a cowboy server +</I>>><i> and this process needs to periodically send text to all http clients +</I>>><i> connected to the cowboy server.
