Does the client close the connection?  Why do you think that it
moves on to the next request?

Despite repeated requests for more information, you haven't told
us much of anything at all about the client or your setup.  I
gather that the client is something you wrote yourself; why not
put that code somewhere for someone else to inspect and
understand?

You haven't shown sufficient evidence to support that
conclusion; perhaps you have it, but you haven't shared
it.  Have you even attempted any of the debugging steps
I suggested to you, for instance?

Yes.  I don't see any evidence to support your claims.
