Matching HTTP traffic to TCP

I've a hunt for an answer to this question but can't find it...

I've got a pcap for a webpage loading and I want to match the HTTP requests to TCP conversations

The HTTP requests have a cookie that's larger than the TCP segment size and I want to check whether the client is waiting for an ACK before sending the rest of the HTTP request.

Can anyone advise how I do this or point me at a tutorial for it?

EDIT

OK made some progress, by finding the tcp.stream and filtering on it I can see all the packets on that stream.
