p0c has asked for the wisdom of the Perl Monks concerning the following question:

Hey all, I'm looking for some modules or example script on how to capture packets, modify and then send them further. Net::Packet is good for capturing, but I can't see how to edit the packets. I can only manage to look at the packet itself, but the packet itself is already send to it final destination then. Maybe Net::Packet isn't the right way to go? Say for example I want to replace <img src=bla.jpg> to <img src=lala.jpg> in every HTTP packet.. Can anyone give me some pointers in the right direction?
