Subject [jira] [Resolved] (HTTPCLIENT-1729) Evicting Stale connections from the connection pool
Date Wed, 09 Mar 2016 08:48:40 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1729?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Oleg Kalnichevski resolved HTTPCLIENT-1729.
-------------------------------------------
       Resolution: Invalid
    Fix Version/s:     (was: 4.5.3)

As I said already stale connection check and connection expiry time are _absolutely_ unrelated.


I am not sure I understand what exactly you mean by 'how to handle stale connection checks'.
You need to configure the connection manager to do what is appropriate for your particular
application.

Please do not re-open the issue.

>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>    Affects Versions: 4.5.2
>            Reporter: Manikandan Subramanian
>            Priority: Minor

> 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.
