I've got a situation where none of my servers can view the actual resources
from the uiuc domain. They can all browse to any subdirectory and can look
at the metadata for any resource. But they can't see the contents of a
resource file. The window that shows the rendered resource does open but
just has the one line "Unable to find SomeFileName.problem" for problems

in the binghamton domain. However, I can see resources on other domains
(e.g. msu) that are
Using nmap against library1.lon-capa.uiuc.edu shows port 443 open.
