Hi, recently I found that if I start a session and cancel it after a second, repeat the same request for about ten or more times, then when a new request is started, in http proxy I found this new request will always gets time out. But if I debug the request in somethings like postman, the request is finished ok. So the server seems ok, but the client, it's iOS, is not.
So I changed my solution, and every time when I want to get a new task, I create a new `URLSession`, the problem still exists, except now I should retry creating tasks and canceling for about 50 times. And sometimes the request isn't seeied in http proxy, it seems the URLSession doesn't start the tasks.
I can guarantee that I'am using HTTP 2.0
Some thoughts about this?
