Could you please add detail information in the issue?

@mapleegreen,
Could you let us know what’s the size of data the server sent to you?

I tried to send 1MB data to server in HttpClientTest, and after some minutes, I did receive 1MB data.
So could you please describe more about how to reproduce this problem?Thanks.
