single dot in URL for BasicURLNormalizer

[Mingfai]

hi,

The BasicURLNormalizer removes "../" from URL. I wonder if "./" should be
removed, too? is it functionally valid in HTTP? how about removing "/./"?

The current behavior is as follows:
        assertEquals("http://www.apache.org/";, normalizer.normalize("
http://www.apache.org";, null));
        assertEquals("http://www.apache.org/style/style.css";,
normalizer.normalize("http://www.apache.org/../style/style.css",null));
        assertEquals("http://www.apache.org/./style/style.css";,
normalizer.normalize("http://www.apache.org/./style/style.css",null));

For the above specific case, it's ok to remove the "./"
        assertEquals("http://www.apache.org/style/style.css";,
normalizer.normalize("http://www.apache.org/./style/style.css",null));
//functionally ok, the test case fail.

p.s. is there any test case for BasicURLNormalizer? I can't find a
TestBasicURLNormalizer.java and wonder if similar functional test exists in
another test case.

Thanks and regards,
