/**
|
|
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=10
|
|
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 a it leaves some spare handlers in memory to improve
|
|
performance.
|
