Oleg Kalnichevski commented on HTTPCLIENT-1000:
-----------------------------------------------
> as long as a connection is being used its expiry can continuously be pushed
> back, and the connection will last indefinitely
I see.
> Could you elaborate more on what adding methods to ManagedClientConnection
> would break?
Binary and API compatibility with 4.0 releases. 4.1 will no longer be
compatible with applications that have custom implementations of
ManagedClientConnection interface.

> Configure Maximum Connection Lifetimes
> --------------------------------------
>
> Key: HTTPCLIENT-1000
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1000
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Components: HttpClient
> Reporter: Michajlo Matijkiw
>
> Provide a means of configuring a maximum lifetime for HttpClient connections.
> Currently, it would appear as long as a connection is used it may persist
> indefinitely.
> This would be useful for situations where HttpClient needs to react to DNS
> changes, such as the following situation that may occur when using DNS load
> balancing:
> - HttpClient maintains connections to example.com which resolves to IP A
> - Machine at IP A fails, and example.com now resolves to backup machine at
> IP B
> - Since IP A is failing, connections are destroyed, and new connections are
> made to IP B
> - Machine at IP A recovers, but HttpClient maintains connections to IP B
> since the connections are still healthy
> The desired behavior would be that connections to IP B will reach their
> connection lifetime, and new connections could be created back to IP A
> according to the updated DNS settings.
