Yes, I thought I already answered this question from you.
I don't know that I consider this a bug. It "updates" the db by checking
all the URLs in the database. Basically, it generates a list of all the
URLs in the DB and then checks them for changes.

On an update dig, ht://Dig sends an If-Modified-Since header. It does this
as a GET because it wants to make one connection. The HTTP specification
says that this header will return the document if it's modified and an
error code (I forget off the top of my head) if it's not modified.
I've noticed this header does not always work. However, in version 3.1.0
and on, after recieving the data, htdig checks the date in the header
before parsing it. So even if the server incorrectly sends the data,
ht://Dig won't bother continuing.

You have an old version of ht://Dig. This was a bug fixed in version
