I just started to use htdig on our site and I'm really
impressed with the results (say bye bye to Excite for
Web Servers :)). I will definitely use it to index
our site (http://www.opera.it).
I have another (much bigger) project, though, and I need
your opinion to understand if it's feasible and if so
what would be the best way to implement it. While I don't
pretend to use htdig as another "Altavista", I would love
to use it to index the opera sources on the Internet. I'm
talking about maybe 2-300 sites worldwide, most of them
with just a few pages (the average might be 7-10 pages
per site), so I understand that size shouldn't be a big
issue. Should the number of sites be a problem, I might
reduce it to the most important 50-100 of them.
The biggest problem, however, would be the "digging" part:
here in Italy bandwith costs a *lot* and every single
bit is precious, so it would be really great if I could
index these sites nightly, when the bandwith usage is
much lower. I did a few tests tough, and found that I need
about 20 hours to gather all the material: I need than
to be able to do a "partial" digging (say 2 hours per night,
or even less), so that every 10-15 days the database
gets updated without hurting too much the bandwidth.
Is there a way to do that? I understand that the "-a"
option might be helpful, since it keeps a copy of the
existing database, but I don't see how I can tell
htdig to "resume" a suspended run (and even how to
suspend it: I don't know if htdig would behave if I
send him SIGSTOPs and SIGCONTs via cron).
I'd appreciate a lot even pointers to documentations,
FAQ and such. Also, if you think that there are better
softwares to accomplish this task suggestions would
be most welcome :)
Thanks in advance for your help,
