Re: CGIs to manage backlink information

Hi Ping,

Yep, I saw your pages (sure you can check your logs last week for
hits from .unizar.es... well, or  from .infn.it as we sometimes chained. 
our cache to the italian one). In fact I included your node in the
references of my paper (PAPER224.html). Of every the backlinks projects I 
revised, it is the the one I like more. 

Althougth, I didn't found in your pages any technical
explanation, so I only could guess. I supossed you do some
post-process of the referer log, as to read the referer html is 
a bit time consuming. Note that I can not do such check in my 
method, as in works on real time, and if we open a internet
socket for each hit we got, our machine can be saturated two times
faster than with normal use. If servers eventually come to give al
the link information with only a HTTP HEAD, it could be done. 

Probably both methods would complement. Real-time capture and
insertion has a nice feedback... link is seen next time page
is downloaded, in the same page. Some periodical script would check
both for obsolete and false backlinks. 

It would be nice if you had some time to write down a 
report of your experience.
