cNo The Mirror is just a quick thing I'm making to test a project that will give people the ability to seed ImageBoards, similar to the way people seed BitTorrent. Because I can't edit the pages directly on the ImageBoard servers (the project is still experimental, I wouldn't want to yet), I'm making a mirror of those pages and making the few small changes to them needed. The Primary change is taking every thumbnail link and changing them to something like;
(Adding the ImageBoard-Tracker's address before the target URL)
If you navigate to that URL, and you right click on the image and go to properties, you will notice that the image shown to you is NOT from imageboards.4-ch.net. It redirects to one of the gseedersh of the ImageBoard. Of course, this project is still in the experimental stage, so there are no real seeders, but I set one up with my SF space and edited the settings files so they see SF as a seeder.
Go to http://seeder-chan.sourceforge.net/ and read up on it there.
