Hi, when I append dir=./. to an URI, the page load without stylesheet...

Normal page: http://www.w3.org/Style/CSS/
Error page: http://www.w3.org/Style/CSS/?dir=./.

Normal page: http://www.litoweb.net/pfn2/
Error page: http://www.litoweb.net/pfn2/dir=./.

Why?, I don't know.

Reproducible: Sometimes

Steps to Reproduce:
1. Write http://www.w3.org/Style/CSS/ to see the page fine
2. Write http://www.w3.org/Style/CSS/?dir=./. to see the page bad



I'm using Ubuntu Linux 5.10

I'm code an application that use dir var in URI and sometimes with some dir value, the web crash.

The urls in the error examples don't link to ?dir=./. they are linking to ?dir=./ in the a href

please make sure that the url that you try is ?dir=./.

This does cause a problem, but then the URL that causes the problem is invalid. A / should be represented as %2f in the query string, so I'm not sure if this is an actual bug or something that cant be helped when using invalid urls.

Confirmed.
After some testing, I can say that this only appears to manifest itself if the "?dir=./." is appended to a subdirectory (not the host alone).
I'd say this was invalid.

The stylesheets use relative links in the source. Given the dir=./. URL, the browser attempts to load, e.g.
http://www.w3.org/Style/CSS../threepart-f.css
whereas given the normal URL, the brower attempts to load
http://www.w3.org/Style/threepart-f.css

I don't feel like going through the spec to see if this is right, though.

Also, the "dir=" isn't required, it works just the same with ?blah=./. or even just ?./.

If you can come up with a compelling reason to make such invalid URLs work, please re-open this bug report.
