<p class="MsoNormal"><span style="font-family:"Times New Roman""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">This is question about configuring nginx so that when you have multiple servers in an upstream block and the first one selected to handle a request "times out" (at default 60s) that we can skip
the forwarding to subseqnt servers in the upstream block.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">We see the case where the upstream_response_time in nginx log shows like 60s,60s.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">We have a client that aborts the request/connection at 20sec and other clients that ultimately fail because the server responded with failure with the 60s,60s upstream_response time.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">We want to institutionalize the aggregate 20s round trip client request time at the server side if possible.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">In other words we don't want to configure the proxy read and write timeout settings to 20 as this might result in total of 40s as observed by the client.<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">We don't want to set the seetings to like 10s as that may not give the server enough time to complete processing.<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">Rather we want the proxy read write timeouts to be 20s and the entire request to fail immediately without going to the next server in the upstream block.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">How is nginx configured so if the first upstream server times-out; then subsequent servers are not consulted and the server effectively timeout at 20?</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">I hope this makes sense</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:16.0pt;color:black">Thanks</span><o:p></o:p></p>
