Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the address@hidden mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Run 'emacs -Q' and then evaluate this in *scratch*:
(url-retrieve-synchronously "https://api.del.icio.us/v1/posts/update")
Two " *http..." buffers are created. The first contains a page with an
HTTP status of 401 saying that authentication is required. The second
(after I type my username and password) contains the text of the page I
was trying to reach.
url-retrieve-synchronously returns the first buffer instead of the
second. If I run url-retrieve-synchronously again the authentication is
cached so there's no 401 to worry about and everything works.
I can make it break over and over again if I empty the auth cache as
follows and try again:
(setq url-http-real-basic-auth-storage nil)
You'll need a del.icio.us username and password to test. I haven't
found another site at which I can reproduce the problem. I've never
been able to understand how url-retrieve{,-synchronously} really works
so I probably won't be much help at figuring out what's going on.
Here's the debug output (from *URL-DEBUG*):
