Note that options cannot be changed on a request once it is added to a HttpRequestPool. The pool reads the options and uses the values as they were set at the time it was added.
This means you can't do things like dynamically change the timeout each time you receive some data from the stream (essentially creating an idle timeout when doing things like calling remote long-running jobs). However you can use low_speed_limit and low_speed_time options to simulate this behavior.
