Hi

I'm modifing a Datagram raw TCP IP, because I want to change the cookie of a web page, when I modified the datagram the browser hangs, So I think that could be, maybe because I´m not updating all TCP IP necessary Headers, I updated the PAYLOAD SIZE, IP Total length, IP Checksum, I dont see if I need change another one.  Maybe because the IP length is 1470 and after the changes is 1481, and that's in the edge (1500). I dont know, somebody can helps?.  

I'm using divert sockets, that why I change in TCP IP
