That is being sent out. Sure, it will block when the outgoing buffer gets full. But, that isn't a problem.
Yes - but since he is stating that on the server side he is only receiving
server only shows this a=0.00&b=37
that seems to indicate that something is happening with the buffer. as we don't know how this is setup and how often he loops this... wondering how the buffer plays with the dynamic String objects he is playing with...

Yes - but may be not enough.
indeed would be on safer grounds with a char array.
