Re: Bureaucratic nightmare for an ISP
But what if a page was not properly marked as dynamic? I'd be POed if I couldn't see new posts on one of my favorite forums. If I wanted caching, I'd just run squid on my server.
Also, how would a web cache detect http traffic? Would it just pass all port 80 traffic. What about sites on port 83? What about sites on port 1351 or 8684? |

As long as the page is written correctly, the author will have included a tag noting the dynamic content, which will then not be cached |

said by vpoko :You know, that's really not an entirely facetious solution. If ISP's were to terminate everyone who wanted porn-blocking, other ISP's would begin to cater to those customers (supply and demand). Some ISP's would be porn-friendly and some would block it for everyone; the problem of having to maintain lists is solved. Again, the lists wouldn't need to be maintained by individual ISPs. Most likely, it could be implemented in the form of DNSBLs.

said by reub2000 :Which would have a bit of overhead. I hope it doesn't add too much though. Use of proxies can improve web content viewing. That's the whole premise behind a content-accelerator: you proxy a group of users behind a caching device. The first person to visit a site experiences a small access-time penalty (generally not something noticeable). All subsequent visitors for the target site fetch content from the local cache, not the remote site. Therefore, their fetches are done from closer hosts, thereby accelerating downloads (since the fetches are only going one or two hops, not tens of hops).

said by TKJunkMail :said by vpoko :Well, they don't really have to maintain a list of IP addresses. The government supplies them a list of URL's and they can just block those URL's at the DNS level. If someone wants to access a porn site by typing in its IP address, that's technically different from the using the URL. I meant customer IP's, not the list of porn IP's. But you bring up a good point on how do you implement this so that some customers can block the porn sites and some can see the porn sites. Do you force customers thru the DHCP procedure to use different DNS servers(1 for porn and 1 for no-porn). Which is easily overridden, even by non-geek children, in the routers setup and in the pc's browser config. Or do you force all subscribers who want no-porn to go thru a proxy server, which would be the only IP address accessible thru a restrictive setup in the cable or DSL modem. Or are their easier ways on how to differentiate between porn and no-porn customers. .
Set up your POP routers to do packet inspection.
Well, if they're using PPPoE for connectivity, there's already a level of authentication that could be used to apply profiles to a connection (e.g., force specific accounts through filtered proxies). A possibly more brute force method would be to send all users through HTTP proxies. Enable authentication on the proxies. Customers that have selected porn filtering get additional content-filtering rules applied to their sessions. Users not in the filtered class don't have the content-filtering rules applied.
Doable, but not something that most ISP engineers are likely to be happy to do.

I'd be pretty pissed if my tax dollars were going to paying people to maintain this list. This list would have to be ungodfully long and exhaustive to do any good at all.
If I as a consumer don't want porn I simply just don't browse to that porn site. If I do want porn than I do. If I have kids that I don't want browsing to said sites I go and get some software to do it. If there's a big enough market for this then ISP would be happy to do this for a fee. If there isn't then why should the government subsidize something there's no market for?

Since its just blocking a list of porn sites, Id think they'd just send all the http traffic through a transparent proxy. |
