I have a packet dump of an ISO file being sent over an HTTP request, and I would like to reconstruct the actual image. I am familiar with the Net::Pcap and NetPacket::* modules and have used them for extracting other statistical data from the stream, but there is no readily apparent way to take the TCP conversation that I have and translate it into the resultant file as it would have been reassambled on the end host. Are there any good libraries for accomplishing this task?

Update: I managed to successfully extract the HTTP conversation using tcpflow, and then to extract the ISO from that by writing a simple Perl script to strip off the leading headers. The recovered ISO seems to be good. Thanks to kvale for the tip.
