Hi sorry I havent looked through the FAQ yet for this but I figured it'd be a specific/complex enough question that it's not in the FAQ and my laptop's almost dead w/o my p/s around... hopefully this is just a quick answer for somebody with more knowlege than myself, I'll try to check tomorrow for any replies... can anyone explain to me (the theory) of ... say there's workstation A- logged on to the internet, surfing webpages, and there's workstation B (say someone like a spammer or advertiser who would want to deliver a webpage to workstation A for marketing purposes with their message and or slogan)...

say workstation B wants to send- or rather *force* a page open (like a popup) on to workstation A's box... isn't port 80 in like a "listen" mode normally for requests?? or... basically what I'm wanting to know is what stops this?? Or is it not normally prevented? I will search the faq for how popups work... maybe that's what I should be reading to answer my question. Just in case, I'll post this. Thanks for any help!!
