Hello there For the first time in a long time I have some time to play around with my ISA's and I want to expend some time working on HTTP filtering. The thing is, how seeing the packets on my NetMon3 Beta (Thanks Jim) I know the signatures of the product used to generate that HTTP traffic? For example, which one is the signature for Internet Explorer and which one for Firefox? To by that way be able to filter traffic generated from one and not the other one. Sorry if my question is kind of stupid but I have no idea about this topic. If you know about some documents online, please let me know. Thanks guys Regards Diego R. Pietruszka
