For a given definition of "urgent". URL removal has to be instead of, not in addition to, a 410 ("gone") or 301 ("permanent redirect"). Or at least a "disallow" in robots.txt.
There is any number of different ways to keep humans and/or robots out of files and/or directories. Which one you use depends on the exact circumstances and on what else you already have going on in your htaccess or config file. You rarely need to identify your domain name, since that's implicit in the location of the file.
Thanks,Lucy24. Guess I'll disallow the dead pages until they go away. My urgency in url removal was when I saw old pages in Way Back Machine and Gigablast full of red x'd boxes from deleted pics. I was horrified! Sad thing is, those SE's rarely visit and won't see a code to update it.
