Hello,&lt;br&gt;<br>
&lt;br&gt;<br>
this&nbsp;is&nbsp;somewhat&nbsp;similar&nbsp;to&nbsp;what&nbsp;someone&nbsp;else&nbsp;has&nbsp;asked:&lt;br&gt;<br>
&lt;a&nbsp;href=&quot;http://lists.ninenines.eu:81/archives/extend/2013-August/000224.html&quot;&nbsp;target=&quot;_blank&quot;&gt;http://lists.ninenines.eu:81/&lt;u&gt;&lt;/u&gt;archives/extend/2013-August/&lt;u&gt;&lt;/u&gt;000224.html&lt;/a&gt;&lt;br&gt;<br>
&lt;br&gt;<br>
I&nbsp;am&nbsp;new&nbsp;to&nbsp;cowboy,&nbsp;I&nbsp;have&nbsp;a&nbsp;process&nbsp;that&nbsp;runs&nbsp;alongside&nbsp;a&nbsp;cowboy&nbsp;server&lt;br&gt;<br>
and&nbsp;this&nbsp;process&nbsp;needs&nbsp;to&nbsp;periodically&nbsp;send&nbsp;text&nbsp;to&nbsp;all&nbsp;http&nbsp;clients&lt;br&gt;<br>
connected&nbsp;to&nbsp;the&nbsp;cowboy&nbsp;server.&nbsp;My&nbsp;goal&nbsp;is&nbsp;to&nbsp;have&nbsp;a&nbsp;streaming&lt;br&gt;<br>
connection&nbsp;for&nbsp;each&nbsp;http&nbsp;client&nbsp;so&nbsp;that&nbsp;I&nbsp;could&nbsp;stream&nbsp;text&nbsp;to&nbsp;them&nbsp;from&lt;br&gt;<br>
my&nbsp;process.&nbsp;how&nbsp;is&nbsp;this&nbsp;done?&lt;br&gt;<br>
&lt;/blockquote&gt;<br>
&lt;br&gt;&lt;/div&gt;&lt;/div&gt;<br>
Same&nbsp;answer&nbsp;really.&nbsp;You&nbsp;need&nbsp;some&nbsp;kind&nbsp;of&nbsp;process&nbsp;registry,&nbsp;like&nbsp;gproc&nbsp;properties&nbsp;for&nbsp;example,&nbsp;that&nbsp;will&nbsp;store&nbsp;all&nbsp;Pids&nbsp;and&nbsp;allow&nbsp;you&nbsp;to&nbsp;send&nbsp;a&nbsp;message&nbsp;to&nbsp;all&nbsp;of&nbsp;them.&lt;br&gt;<br>
&lt;br&gt;<br>
On&nbsp;init,&nbsp;register&nbsp;the&nbsp;process,&nbsp;and&nbsp;then&nbsp;handle&nbsp;the&nbsp;incoming&nbsp;message&nbsp;when&nbsp;it&nbsp;arrives.&lt;span&nbsp;class=&quot;HOEnZb&quot;&gt;&lt;font&nbsp;color=&quot;#888888&quot;&gt;&lt;br&gt;<br>
