[freenet-chat] ActiveLinks

2002-09-17 Thread Josh Steiner

I was wondering a little bit about activelinks.  they are proported to 
encourage the continued propagation of free sites, but I dont see how 
the do anything but encourage the propagation of the activelinks 
themselves.  as i understand it, each of the keys that comprise a 
freesite will have wildly different domains, so propagating one key 
should have no bearing on the other keys in the same freesite.  do they 
actually do what TFE claims they do, and how?

later.

Well, I don't know exactly what TFE has in mind when those claims were made,
but...

Whenever you have an SSK with a double slash // in it, that refers to
a mapfile.  These activelinks generally look something like:
SSK@pubkey/sitename//activelink.jpg

In order to fetch activelink.jpg, you first have to fetch the mapfile.
In order to fetch the mapfile, you might need to grab a DBR redirect
first.  The mapfile of course is the master index that lists all of the
files that the site provides and how to get them.

By downloading the activelink, you ARE spreading the DBR redirect and
the mapfile for the freesite on which the activelink resides.  That's
why people link activelinks directly to other people's SSKs rather than
saving the activelink, and inserting it under their own SSK - certainly
that would work, but it wouldn't spread the other site's mapfile.

So this doesn't help you fetch the front page of the site, but it spreads
data that is vital to the site's ability to be seen by others, namely
the mapfile.  Also, *generally* (not always) if you can fetch the activelink
that means that rest of the site will be fetchable.  If it's not fetchable,
it often means the rest of the site wasn't inserted at all (in the case of
editions not yet published) or misinserted.

Hope this helps.
