You mean by reading other site's cookies? How do you use my credit card number if I'm shopping at ebay which prefetches your site (for which the ebay webmaster should be hung anyway) and the only thing you see is the Referrer. What is the difference between automatic pre-loading and simultaneous browsing for example? These bugs will always be in browsers and one feature on top of that doesn't change a damn thing. And even that page talks about having a knob for all this, which is why this discussion started - let the user decide - if he thinks he knows better, it's his choice. for Claudio: Yes, it does use bandwidth. That's what bandwidth is for. And it's not "browser decides", it's "web creator decides" and despite that it will surely be abused, many sites (like news) might benefit from that. Of course, the right way to do it is blocking all the ads, flash and javascript using a proxy and not really being concerned about idiots thinking their website is "cooler". But from the user's point of view it doesn't matter - it's just slow. And I don't know if as a public ISP you would start blocking shit that makes pages that people visit slow, how long would it take for someone to notice and start complaining. Even if these filters were perfect. Honestly, how much of your network's traffic is the web? Even those rapidshares full of illegal shit aren't that much of a burden, because everyone is behind 1 or 2 IPs and these sites usually provide content per IP. > On some sites you will end up pre-fetching decent amount of pron, > trojans, whatever because browser decided "you might visit in the > near future". It's not "whatever browser decided you might visit", it's what the creator of the page decided. So yes, if you are on some warez page, you have higher chance of prefetching potentially malicious crap, but (as was written on the page you linked) the creator can use javascript to trigger the same kind of effect, maybe with lower impact on your browser cache. And he will probably eat up more of your resources that way, which is basically why you need a quad core for surfing the web in Windows these days. It's not the amount of data, it's the way they're processed and served. Try telling some random BFU he should disable javascript for a week. He'll laugh at you then. I believe the right place for this is misc@. -- Martin Pelikan
