title: What causes a jetty idletimeout
body: <p>Our server is using clojure ring.adapter.jetty and one of our users is causing a <code>java.io.IOException: java.util.concurrent.TimeoutException: Idle timeout expired: 200000/200000 ms</code> error when uploading a large(ish) file, ~20MB.  He has a very slow connection, but I dont get the same error throttling my connection. The timeout exception is high enough (this is the idle timeout, not upload timeout)</p>
  
  <p>The quick version of our upload process is using a multi-part form, and then copying the temp file to the server folder with java.io.copy.</p>
  
  <p>I am trying to at minimum re-create the error with my machine to get error handling working. If I find any solutions that change my application code, I need to test them as well by trying to cause the error.  So far I tried throttle my speed to as close to 0 as it will allow, and setting a super high latency in devtools (chrome), and set the jetty timeouts to 100ms but it still uploads fine.</p>
  
  <p>Is there also anything the user can do to help reduce the chance of a timeout.</p>
