Well, one minor flaw... you have the wrong base URL.
You *definitely* would never have X/~boris as a page, unless
you happen to have a file named ~boris somewhere.
More likely, the base URL should be X/~boris/ (note trailing slash)
which your server would have redirected you to immediately when you
asked for the first.
And yes, this *does* make a difference on relative URLs, and it's *why*
the server issues a redirect.
There is *no* page named X/~boris !!!
However, I'm still mixed about where ../.. should really abs to,
because I think any sane web-server will give you back a redirect to
the real page. (Didn't try this though...) Maybe the relative URL is
illegal, and how URI::URL responds to illegal combos is probably
undefined, although if it's illegal, it should give a useful
result. :-)
Ahh.. just tried it with Apache 1.1, and it gave me a 400 error.
So there'd be no chance that a 'bot could get lost... it'd die on the
absolute URL.
