> @ok2c @rschmitt can you help me with the problem when I use the
httpAsyncClient( httpclient 5.4.3 、jdk 21) First, I set a 100-second sleep on
the server side to ensure that no response is returned within 100 seconds.
Second I use the `RequestConfig.setResponseTimeout(Timeout.ofMilliseconds(50))`
to set the response timeout value on the client side.
>
> I have modified the timeout multiple times and obtained the following
results. `[async]failed is 1 MILLISECONDS, time usage is 1033`（1 MILLISECONDS
means I set the ResponseTimeout as 1ms, time usage means that client side
timeout after 1033ms） `[async]failed is 10 MILLISECONDS, time usage is 1010`
`[async]failed is 500 MILLISECONDS, time usage is 1015`
>
> `[async]failed is 1000 MILLISECONDS, time usage is 1013` This is the
expected value. `[async]failed is 1020 MILLISECONDS, time usage is 2019` ......
>
> **It seems that the effected ResponseTimeout is being rounded up to the
nearest second, and milliseconds are not taking effect.**
>
> In addition, I used a synchronous httpclient, which works well. I set the
ResponseTimeout = 50ms. `[sync]failed is Read timed out, time usage is 63`
my code is
`
