Oleg Kalnichevski commented on HTTPCLIENT-2028:
-----------------------------------------------
{quote}So failing that what would you suggest as a workaround, is there a retry
mechanism on stale connection that can be used{quote}
Connection life-time control and proactive eviction of expired connection is
way, way preferred to the stale connection check and request re-execution.
{quote}Also, what's the harm in leaving the ability to do something in future
versions of the library that exists today, nevermind if it works 100% of the
time or not?{quote}
I am not sure why you are saying connection validation has been removed in 5.0
cause as far as I can see it is still there

> Restore staleConnectionCheckEnabled=true semantic behavior in

> --------------------------------------------------------------------------------------------
>
> Key: HTTPCLIENT-2028
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2028
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Components: HttpClient (classic)
> Affects Versions: 4.5, 4.5.1, 4.5.2, 4.5.3, 4.5.4, 4.5.5, 4.5.6, 4.5.7,
> 4.5.8, 4.5.9, 4.5.10
> Reporter: Peter Frank
> Priority: Major
>
> Between HttpClient 4.4.x and 4.5.x setStaleConnectionCheckEnabled was
> deprecated in favor of setValidateAfterInactivity. That's all fine, however,
> the implementation of setValidateAfterInactivity has no ability to check if a
> connection is stale all the time. The closest one can get is 1 ms, and
> that's unfortunately not short enough in a test environment scenario when a
> test Http Server is being restarted between Tests to clear out state.
> This is a common issue on the internet for people that use something like
> Wiremock, the irony is troubleshooting the situation makes it go away (cause
> logging slows the tests).
> I would suggest making 0 a special value to "turn on" validation all the time.
> With HttpClient 5 removing the old staleConnectionCheckEnabled completely
> with a piece of what that feature actually did also being removed I fear it
> will leave me, and perhaps others, in a bit of a lurch. Thanks!
