I have a query for the Chemistry-Internet community at-large, but particularly for industrial sites. Our corporate IT department recently completed the installation of a firewall/proxy for all Internet traffic and one of the "protections" they have implemented is a filtering process that prohibits access to certain URLs (sites) - some explicitly and others by somewhat generic rules. One such generic rule is the the presence of a tilde (~) in the URL. Tilde's are often used as a shortcut representation of a home directory (particularly on Unix systems). For some reason our IT department considers such sites as inappropriate for business/research purposes. It now take VP approval to unblock such sites. Has anyone else heard of, experienced, or fully understand such a policy?
