I wonder if there is a way in wireshark to reconstruct a complete TCP Session (HTML page(s)) if we have wireshark pcaps, can wireshark do the reconstruction? or is there any
Depending on what version of Wireshark you have, you should be able to do something along the lines of:
Is there something more you need... this appears to do the gzip decompression etc... won't work if you're running SSL (it MIGHT be able to if you can get the appropiate keys to make the SSL decode work, but that gets trickier and I'd suggest trying fiddler in that case)
