Re: Bureaucratic nightmare for an ISP
Since its just blocking a list of porn sites, Id think they'd just send all the http traffic through a transparent proxy. |

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).

@silvereaglemfg.com | 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 |

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? |
