Ignat Alexeyenko commented on HTTPCORE-341:
-------------------------------------------
Oleg, that all makes sense.
What do you think about adding these responsibilities to
PoolingClientAsyncConnectionManager? Could you review this class?
I think we can change it it, to free connections before leasing new ones:
this.closeExpiredConnections()
this.pool.lease(route, state, connectTimeout, tunit, new
InternalPoolEntryCallback(future));
Another option I see is to add these responsibilities to
PoolingClientAsyncConnectionManager or DefaultAsyncRequestDirector.
I know that this rather HTTPASYNC
If I'm not mistaken, the this.closeExpiredConnections() seems to be never used
in http client.

> Currently the AbstractNIOConnPool is capable to handle timeouts for en-queued
> requests (requests added in leasingRequests connection).
> What AbstractNIOConnPool - deal with slow connections, that already are open
> and being executed. Slow connections are connections that are not completed
> withing some request processing timeout.
> Example. Consider a specific case, when a remote server holds a connection
> open, but transmits information slowly (e.g. 8 bytes in each 100ms). In
> application under the high load it means that we would stuck with no free
> connections to process new requests for a long period of time.
> In such cases, as a developer I want to specify time in which we would close
> current open connection, even if it is already processing the data.
