It is really unclear on exactly what you are doing and i have no
clue what data is remaining in what buffer you think might be the
problem.

You really dont want to do this. By doing that while loop, you will
do a couple of bad things:
- eating up a lot of CPU usage, of course a sleep in the loop
would probably prevent cpu abuse but still not the ideal way
to do it.
- You will most likely run out of available slots that http has
available.
