Oleg Kalnichevski commented on HTTPASYNC-130:
---------------------------------------------
There is absolutely no problem with using both classic and async HttpClient
implementations in the same application.
BTW, one can greatly reduce the chance of getting {{ConnectionClosedException}}
by limiting connection total time to live or keep-alive time
{code:java}
HttpAsyncClients.custom()
.setKeepAliveStrategy(new DefaultConnectionKeepAliveStrategy() {
@Override
public long getKeepAliveDuration(final HttpResponse response, final
HttpContext context) {
long keepAliveTime = super.getKeepAliveDuration(response,
context);
if (keepAliveTime < 0) {
keepAliveTime = TimeUnit.SECONDS.toMillis(30);
}
return keepAliveTime;
}
});
{code}
