You bet. My full scans take several hours and the "update" take about 1/2
hr. You do this by NOT specifying '-i' to htdig and ensuring you keep the
db.wordlist.work and db.docdb.work files around. I can post my script if
people want it (it's going to go up in the contrib section of the website,
once it gets going).

You can do that. I have a similar setup (some files not available outside
williams.edu). We assume that search results don't return anything too
useful and following the link will fail for outsiders. If they all fall
into neat directories, you can also specify:
<input name="exclude" type="hidden" value="exclude1|exclude2|exclude3">
This will ensure directories exclude1/ exclude2/ and exclude3/ don't show
up in search results.

You bet. One of my "blue sky" projects is to get a Perl script that reads
in a bunch of regexp and uses them to send broken link reports. Right now
I just have a simple script that goes through and reports broken links for

I've been through the code several times. I'd feel safer if a real
security guru went through it. I see no possibilities for buffer overflow
and the variables are pretty carefully screened. For example, the config
field cannot contain a period, so you can't do ../../../../../etc/passwd
