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).
I'm darned if I know. I simply know that it isn't right for http resources. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://holdenweb.blogspot.com Recent Ramblings http://del.icio.us/steve.holden
