networking - Dont send ACK after server response

Question

Hey i have a quick question about some ssl stuff. Is there any way NOT to send acknowledgement (ACK) back to the server after its response?

What am i doing, is testing a friends webapp, written in PHP i suppose, but i don't have a source code, and i think this is more of a general thing. What am i doing is asking a server for some data, handshake happens, i receive data and send ACK that the data were recieved. Then the server "FIN" the connection.. Thats what usually happens, but i'm using Burp proxy to intercept the servers response and noticed that if i drop the response the connection state is on "CLOSE_WAIT" and i don't receive the FIN signal after that, but the server know that i received the data.

So is there any way not to tell the server that i received the data? Basically fake that the data were lost somewhere, but still look at the response? Can Burp Suite do something similar to this or do you know any handy tools that might help? I can provide more info you want.

Thanks a lot!<3
