  finally

  end;
  StartCnt := lstAcct.items.Count;
  StartTime := Now;

finally
  sl.Free;
end;
end;



end.

回答1:

Right before:

sl.Add('ID='+ lsttemp[0]);

Do:

sl.Clear;

On the first run your "SL" holds the two POST parameters, but unless you clear it on the second run, you just keep adding parameters, confusing the HTTP server you're trying to connect to!

That might not be your only problem, but that's surely one of the problems.
