ActionController::AbstractRequest.relative_url_root = "/myappliveshere".
Amazingly enough, it's special-cased for Apache with FastCGI--if it spots
dispatch.[f]cgi in the right environment variable, then it sets
relative_url_root automatically.  That's why it works with Apache most of
the time :-).  That's the magic I was missing this morning.

So, if you add relative_url_root to environment.rb (or $RELATIVE_URL_ROOT to
the environment) to '/blog', then you can proxy from
http://real-server:80/blog to http://localhost:4123/ (running Mongrel) and
all of the generated URLs work.  But, you won't be able to access the
backend directly for debugging, because it'll be expecting urls that start
at / and generating urls that start with /blog/.

I have a little patch that adds a --prefix flag to Mongrel that sets the
Rails handler URI as well as relative_url_root.  As I mentioned above, it's
not strictly needed, but it'll make life a bit easier for people.  Would
this be something that you'd be interested in applying, or should I go tweak
the Typo docs to explain it away?
