>                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1729
>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>    Affects Versions: 4.5.2
>            Reporter: Manikandan Subramanian
>            Priority: Minor
>              Labels: newbie, performance
>             Fix For: 4.5.3
>
>
> This is not a bug. But more of a guidance needed here.
> The below documentation suggests
> https://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html
> to use a separate monitor thread that calls closeExpiredConnections() method for stale connection handling.
> Is this still applicable for 4.5.2 version as well ? I am looking at source code PoolingHttpClientConnectionManager#closeExpiredConnections which in turn calls the pool#closeExpired.
> The closeExpired method checks only the expiration of the connections. However there seems to be no check on whether the connection is stale.
> Should we still handle stale connections checks when using Apache HttpClient 4.5 ? What is the guidance here ?
> Minor possible documentation issue 
> http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/conn/PoolingHttpClientConnectionManager.html
> The above java doc claims that the default timeout that is used before a stale connection check is performed is 5000 ms. However the source code is setting the value to 2000ms. Please correct me if I am wrong.
