Wireshark · Wireshark-users: [Wireshark-users] Merging HTTP packets

[Yang Zhang <yanghatespam@xxxxxxxxx>]

Hi, I captured some packets with the filter "tcp port 80 and host 
www.facebook.com".  As a result I see a bunch of individual packets - 
some HTTP, some just TCP, with many of the HTTP messages segmented.

I can ignore the TCP-only packets by typing in 'http' in the filter box, 
but is there some way to merge the HTTP packets to be whole, unsegmented 
requests/responses?

If wireshark is the wrong tool for this level of analysis, then are 
there any recommendations of a better tool?

Thanks!
