I am now developing a project using Winpcap.. I know that packets being sniffed are usually fragmented packets.

How can I reassemble these TCP fragments?.. Are any ideas, suggestions, or tutorials available?

I am assuming this to be the only way I can view the HTTP header...

Thanks!

All the TCP packets contain TCP sequence number. To re-assemble the data, you just need to start at the Initial sequence number packet and going from lowest to highest sequence number

TCP header structure[^]

TCP initial sequence number[^]
