&lt;div&nbsp;dir=&quot;ltr&quot;&gt;&lt;div&gt;But&nbsp;then&nbsp;I&nbsp;would&nbsp;have&nbsp;to&nbsp;check&nbsp;the&nbsp;client&nbsp;cert&nbsp;for&nbsp;each&nbsp;and&nbsp;every&nbsp;request. &nbsp;I&nbsp;should&nbsp;have&nbsp;to&nbsp;check&nbsp;the&nbsp;cert&nbsp;only&nbsp;once&nbsp;at&nbsp;connect&nbsp;time&nbsp;and&nbsp;then&nbsp;be&nbsp;able&nbsp;to&nbsp;pass&nbsp;the&nbsp;result&nbsp;of&nbsp;that&nbsp;check&nbsp;in&nbsp;the&nbsp;request&nbsp;to&nbsp;each&nbsp;handler.&lt;br&gt;<br>
&lt;br&gt;&lt;/div&gt;Anyway&nbsp;I&#39;ve&nbsp;gone&nbsp;ahead&nbsp;and&nbsp;implemented&nbsp;what&nbsp;I&nbsp;need&nbsp;in&nbsp;a&nbsp;generic&nbsp;manner&nbsp;and&nbsp;it&nbsp;seems&nbsp;to&nbsp;work&nbsp;well. &nbsp;I&nbsp;think&nbsp;it&nbsp;would&nbsp;be&nbsp;a&nbsp;useful&nbsp;addition&nbsp;to&nbsp;Cowboy. &nbsp;If&nbsp;you&nbsp;agree&nbsp;I&nbsp;could&nbsp;write&nbsp;some&nbsp;more&nbsp;documentation&nbsp;for&nbsp;it.&lt;br&gt;<br>

 &nbsp; &nbsp; &nbsp; &nbsp;I&nbsp;am&nbsp;having&nbsp;very&nbsp;good&nbsp;luck&nbsp;with&nbsp;Cowboy&nbsp;so&nbsp;far,&nbsp;but&nbsp;I&nbsp;have&nbsp;some&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;questions:&lt;br&gt;<br>
&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;1.&nbsp;There&nbsp;doesn&#39;t&nbsp;appear&nbsp;to&nbsp;be&nbsp;any&nbsp;way&nbsp;to&nbsp;do&nbsp;client&nbsp;certificate&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;authorization&nbsp;in&nbsp;Cowboy,&nbsp;although&nbsp;I&nbsp;see&nbsp;there&nbsp;is&nbsp;an&nbsp;example&nbsp;for&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;doing&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;exactly&nbsp;that&nbsp;with&nbsp;Ranch.&nbsp; I&nbsp;think&nbsp;I&nbsp;could&nbsp;modify&nbsp;Cowboy&nbsp;to&nbsp;do&nbsp;what&nbsp;I&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;want,&nbsp;but&nbsp;I&nbsp;thought&nbsp;I&nbsp;would&nbsp;ask&nbsp;if&nbsp;there&nbsp;were&nbsp;other&nbsp;options&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;before&nbsp;doing&lt;br&gt;<br>
 &nbsp; &nbsp; &nbsp; &nbsp;that.&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
 &nbsp; &nbsp;Same&nbsp;as&nbsp;Ranch&nbsp;really,&nbsp;you&nbsp;just&nbsp;gotta&nbsp;take&nbsp;the&nbsp;socket&nbsp;and&nbsp;then&nbsp;call&lt;br&gt;<br>
 &nbsp; &nbsp;the&nbsp;ssl&nbsp;functions.&lt;br&gt;<br>
&lt;br&gt;<br>
&lt;br&gt;<br>
Yes,&nbsp;but&nbsp;in&nbsp;cowboy&nbsp;there&#39;s&nbsp;no&nbsp;API&nbsp;to&nbsp;get&nbsp;at&nbsp;the&nbsp;socket.&lt;br&gt;<br>
&lt;/div&gt;&lt;/blockquote&gt;<br>
&lt;br&gt;<br>
There&nbsp;is&nbsp;the&nbsp;undocumented&nbsp;function&nbsp;cowboy_req:get/1&nbsp;which&nbsp;is&nbsp;meant&nbsp;for&nbsp;that&nbsp;kind&nbsp;of&nbsp;&quot;special&quot;&nbsp;use.&lt;div&nbsp;class=&quot;HOEnZb&quot;&gt;&lt;div&nbsp;class=&quot;h5&quot;&gt;&lt;br&gt;<br>
