Thanks!

Hm, strange.  I don't understand why "." vs. "" makes any difference.
If the effective url is foo/bar/index.html, it should send the request
to "foo/bar/." or "foo/bar/", not to "foo/bar/index.html".

In fact, in my browser (NS 4.78) it doesn't make a difference.  What
browser were you using?

Base HREF insertion sucks.  I believe we'll be able to avoid almost
all cases -- but not yet.
