Men, this is getting me crazy. Let me rephrase the whole thing.
You got an URL of the form:
http://a/../../../foobar.png
If you use Firefox, Chromium, wget, or whatever to retrieve it, the
program will act according to RFC3986 and transform that URL to:
http://a/foobar.png
`url' from Emacs will not, and will fail to retrieve the image.
Now I may be mistaken about where in the code the bug is, but there's a
bug: the `url' functions are unable to fetch such an URL, whereas any
other tool is able to.
In Lisp:
(switch-to-buffer (url-retrieve-synchronously
"http://www.gnu.org/graphics/t-desktop-4-small.jpg"))
=> That works
(switch-to-buffer (url-retrieve-synchronously
"http://www.gnu.org/../graphics/t-desktop-4-small.jpg"))
=> Show a 400 bad request
% wget http://www.gnu.org/../graphics/t-desktop-4-small.jpg
