I agree. I work for an ISP that was investigating implimenting this method, and reported to my superiors that it wouldn't be worth the hardware to impliment it.
I personally think that this whole bogus TLD stuff is a bad idea, and would have had absoltuely no regard for blocking access to these 'sites' if I had implimented the system.
As far as operation, I'm not sure how most ISPs impliment this type of system, but I was planning to use a Layer 3 switch, and pass all port 80 outgoing requests to a SQUID server set in transparent mode. This server pretends that its the remote server, and replies with a spoofed IP to the client. The client actually does resolve the remote host, and operates just like it was connecting directy to it. As with most Layer 3 switches, you can set ignores based on source port, dest IP and whatnot. With SQUID, you can also configure it to ignore (or pass out to the internet without any processing) certain site names (aka *.MP3) that would allow these services to work, as well as allow use of programs that use port 80 for other things.
If your ISP has a technician that knows what they are doing, you would'nt even notice you were behind a transparent proxy.
If your worried about caching of pages, make anti-cache headers. Most transparent proxies make use of smart methods of caching anyhow, such as only storing little (1-5kb) images, and whatnot. Belive it or not, when 250 people a minute start up their IE and hit www.msn.net, caching all the 3kb images can save massivly on bandwidth, and not mess up day-to-day operation.
I agree. You need to look at this from your ISPs standpoint; how much does it cost to transport data? A goddamn lot. If your ISP is trying to save (average says) 20% of it's http traffic, good! Cheaper rates for you and me, and faster reply times.
Perhaps your program should obide by standards, and use a port number that doesnt have a well defined service running on it.
If you notice some tv ads don't include the http:// part. People assume if it ends in dot-com its a web site. When i see something that ends in more than three letters, I assume its a news group. At least keep it three letters, I mean can you imagine www.DrSmith.medicaldoctor? I do however like the idea of h-t-t-p-colon-slash-slash-slash-dot-dot-dot (http://slashdot.dot)
The coders over at Netscape work hard, and they are only human. There's going to be bugs in everything. The discovery of these bugs enables us all to learn from these mistakes and not incorporate them in our own programs. Maybe instead of trashing Netscape, we should dedicated some time in helping.
I don't know about any one else, but I have been using name based Virtual Hosting for quite some time, and so have quite a number of large ISPs in my area. I personally don't foresee a problem meaning that I have yet to receive a complaint about not being able to use my site. Any one using an old browser shouldn't be surfing newer sites anyhow.

Very much agreed. I program PHP most of my day, and I can't imagine speaking 'for open bracket cash i equils zero semi cash i less than four semi cash i plus plus close bracket open brace..' all day long. I would spend most of my day thinking of how to say what I want rather then just typing.
I remember seeing on television a year ago a input device that fits right into your hand, has 5 buttons and using combonations you can make the chars you want. Don't know if this did brackets, semicolons or braces though.
I find with the Internet available to me, TV is unimportant. On my days off now, instead of dragging myself to the television, I simply move over to my swivel chair and click the monitor into the On position (And that's not because the Computer is closer to my bed then the TV). I can find anything I want to hear about on a few select sites rather then having to sort through the crap on the 'News At Noon'.
I recall a show on local TV a few years back that was 2 hours long covering local news events and major global events. As you can guess, that show is no longer seen. It is irrelevant. That amount of 'news' can be absorbed in minutes on their web site, and you don't have to put up with anoying commercial breaks.
Admit it, if you could (I know I would in half a heartbeat) get a Twisted Pair Ethernet jack installed in the back of your head (Matrix all over again) so you could have instant access to the Internet, you would. News articles flying around the mindstorm and saturating every desire for news, weather and sports in seconds. (And would't that zero movement lag be nice in a Brain-Port of Quake III?)
Like most others in my generation, if news events don't directly relate to me, who cares? The mainstream media is about grabbing attention. Only stories relating to tremendous death, distraction, drama, or violence are aired on the first part of the news. With the Internet, less censorship on what we hear about is applied to news stories. The plain truth is what viewers want. Is that not what television news started out as?

I will most likley buy this set, even though I already own the first two on DVD. That paper case the first one came in sux.
I enjoyed Fedora Core 1 for the most part. Updating things was a lot easier with all the registration (or at least the most part) for up2date gone.
I'm pleased with all the new toys in 2.6, and look forward to messing around with them.

I can't wait to see what Hubble produces if/when this technology is applied to the lenses in it.
All I care about is how fast i can frag in Quake.
