One way that information about URLs can become a security
consideration is if, in following a link from a secure document X on
one server, to some document Y on another server, the user agent
tells Y's server that the "Referer" was X. This reveals information
about the supposedly secure document X (first, that it exists, and
second, that it contained a link to Y).
