The problem is that when digging a page like:
if htdig encounters an anchor like <a href="index.asp?date=12/1/98">
where the href isn't fully qualified, i.e. doesn't have a leading slash,
then htdig must make up the new URL by concatenating the new href to the
"base" part of the current URL. There's a bug in URL.cc in that it
doesn't differentiate between slashes before or after the "?" in the
URL above, so when it tries to figure out what the base part of the
current URL is, it just strips off everything after the last slash.
This results in URLs like Adam reported above.
It should first strip off the "?" and everything following it, as
this isn't part of the base. Changing the index.asp CGI script to
generate fully qualified hrefs, or to use %2f in the date query, would
work around this bug, but a fix for the bug would be preferable.
The barely tested patch below should fix this for you. Please try it
out, on 3.1.0b4 preferably, and let us know if it solves the problem.
