Suppose I have a site hosted by a real web server, such as Apache, and
it doesn’t put the site on http://server/. Suppose it puts the site
down in http://server/path/path/path/.
If I call url_for(‘/’) it just passes that thru. (Parenthetically:
Why? What’s the point?)
I need to get the complete path that the server uses to dispatch to
the base of the Rails site. Where is this crumb of data?
