+  Pool of http connection handlers. Connection handlers are created on demand and idle handlers are
+  cleaned up in regular time intervals.
+  <p>
+  Example for the required configuration settings:
+  <code><pre>
+  minThreads=1
+  maxThreads=100
+  cleanupInterval=1000
+  maxRequestSize=16000
+  maxMultiPartSize=1000000
+  </pre></code>
+  The pool is empty initially and grows with the number of concurrent
+  connections. A timer removes one idle connection handler at each
+  interval, but it leaves some spare handlers in memory to improve
+  performance.
+  @see HttpConnectionHandler for description of config settings readTimeout
+  @see HttpRequest for description of config settings maxRequestSize and maxMultiPartSize
