Having said this, Andrew *did* demonstrate quite convincingly that the current urljoin has some fairly egregious directory traversal glitches. Is it really right to punt obvious gotchas like
urlparse.urljoin("http://blah.com/a/b/c", "../../../../")
Ah, but how do you know when that's wrong? At least under ftp:// your root is often a mid-level directory until you change up out of it. http:// will tend to treat the targets as roots, but I don't know that there's any requirement for a /.. to be meaningless (even if it often is). -- Michael Urman http://www.tortall.net/../mu/blog ;)
