&lt;br&gt;<br>
As&nbsp;for&nbsp;the&nbsp;timeout,&nbsp;you&nbsp;can&nbsp;simply&nbsp;use&nbsp;erlang:send_after&nbsp;or&nbsp;something&nbsp;like&nbsp;usual&nbsp;and&nbsp;the&nbsp;message&nbsp;will&nbsp;arrive&nbsp;in&nbsp;info/3.&lt;div&nbsp;class=&quot;im&quot;&gt;&lt;br&gt;<br>

thanks!&lt;br&gt;<br>
&lt;br&gt;<br>
how&nbsp;to&nbsp;implement&nbsp;timeout&nbsp;callback&nbsp;manually?&nbsp;if&nbsp;I&nbsp;had&nbsp;receive&nbsp;then&nbsp;I&lt;br&gt;<br>
would&nbsp;just&nbsp;use&nbsp;timeout&nbsp;clause&nbsp;there,&nbsp;but&nbsp;with&nbsp;the&nbsp;handler&nbsp;I&nbsp;do&nbsp;not&nbsp;know...&lt;br&gt;<br>
&lt;br&gt;<br>
I&nbsp;have&nbsp;doubts&nbsp;about&nbsp;validity&nbsp;of&nbsp;my&nbsp;question&nbsp;on&nbsp;the&nbsp;erlang&nbsp;list.&nbsp; I&nbsp;later&lt;br&gt;<br>
realised&nbsp;that&nbsp;there&nbsp;is&nbsp;no&nbsp;problem&nbsp;receiving&nbsp;messages&nbsp;in&nbsp;my&nbsp;handler&nbsp;from&lt;br&gt;<br>
my&nbsp;upstream&nbsp;process,&nbsp;I&nbsp;can&nbsp;do&nbsp;it&nbsp;fast&nbsp;enough&nbsp;and&nbsp;shove&nbsp;everything&nbsp;to&nbsp;the&lt;br&gt;<br>
response.&nbsp;my&nbsp;real&nbsp;problem&nbsp;is&nbsp;to&nbsp;determine&nbsp;if&nbsp;the&nbsp;http&nbsp;client&nbsp;is&nbsp;reading&lt;br&gt;<br>
fast&nbsp;enough&nbsp;from&nbsp;the&nbsp;response...&lt;br&gt;<br>

 &nbsp; &nbsp;Loop&nbsp;handlers&nbsp;close&nbsp;after&nbsp;a&nbsp;while&nbsp;regardless&nbsp;of&nbsp;what&nbsp;you&nbsp;send,&nbsp;it&lt;br&gt;<br>
 &nbsp; &nbsp;only&nbsp;checks&nbsp;what&nbsp;the&nbsp;client&nbsp;sends.&nbsp;The&nbsp;best&nbsp;way&nbsp;for&nbsp;you&nbsp;would&nbsp;be&nbsp;to&lt;br&gt;<br>
 &nbsp; &nbsp;disable&nbsp;that&nbsp;timeout&nbsp;and&nbsp;handle&nbsp;it&nbsp;manually.&lt;br&gt;<br>
&lt;br&gt;<br>
 &nbsp; &nbsp;As&nbsp;for&nbsp;the&nbsp;second&nbsp;question,&nbsp;I&#39;m&nbsp;still&nbsp;reading&nbsp;the&nbsp;thread&nbsp;on&lt;br&gt;<br>
