He expects http://a.b.c/d/../e/ to be the same as http://a.b.c/e/.

I don't see anything in http://cpansearch.perl.org/src/GAAS/URI-1.58/t/abs.t that covers this case.

The equality definitely doesn't hold up in file systems (due to links both soft and hard), but ../../../y is much less likely to be correct.

Update: Improved test a bit.
