Hello Oleg, Thanks for your response.
What I mean by removing keep alive strategy is the following. I have an administration application with the following option: [x] Keep alive http connection for [ xxxx ] seconds. If the user checks this option, he must enter a number greather than 0 as keep alive duration. Then I set my own KeepAliveStrategy with: this.objHttp.setKeepAliveStrategy(new VPFWConnectionKeepAliveStrategy(keepAliveDuration)); But now imagine that the same user unchecks this option. Then, I should apply the default keep alive strategy. And what is this? Keep alive indefinitely? Pass to 'VPFWConnectionKeepAliveStrategy' an Integer.MAX_VALUE value?

Anyways, you should implement a custom ConnectionKeepAliveStrategy if you want to customize the keep-alive time of persistent connections. If you so not want connections to be kept-alive at all (which is generally not recommended) you should implement a custom ConnectionReuseStrategy. > > > 3.

Without #closeExpiredConnections an expired connection will remain in the pool until a request for a connection lease is made. You may really want to evict expired connections from the pool on a more regular basis.
