getContentLength() returne less then needed size much less I know as a pro this one is of those ones Thanks in any case it will take all my effort P.S if i parse wrongly the page i reload it again so i do it 6 times So i see every time it get more from the page 130k 150k 200k (not round numbers) randomly then after a wile it gets ok and then after a few minutes ( i download every 10 seconds) it breaks down again and so on i wander if it is not time out of http ? Or memory ?
