Summary: redirection error

Initial Comment:
I'm trying to developp a micro browser for a larger
project, using libcurl to handle the network related stuff.
i try to access the following url:
http://xxxxxxx/gestSmsgagn/index_audio.php4?CALLEDNUMBER=%220825105010%22&CMPT%5fAI=2&%5f%5fTIMESLOT%5f%5f=30&%5f%5fDTIDEVICE%5f%5f=dtiB1T11
using a GET method. This script redirect to a relative
path; here's the header of the response:

HTTP/1.1 302 Found

Instead of following the redirection to the url
http://xxxxxxx/gestSmsgagn/sequ_audio/entree.php4 curl
returns an error: "URL using bad/illegal format or
missing URL". The http code is 302 and the effective
uri becomes /sequ_audio/entree.php4 (yes with a slash
at the beginning!).
I know that a redirection must be an absolute url, and
certainly not a relative path, but is this behaviour
something known and not handle or just a bug?

thanks in advance for any response one might give.

should have check 2 hundred times instead of just one hundred.
my fault and mea maxima culpa; the char * i passed for the
uri to get was in fact a not so allocated std::string.
i sincerely apologizes.

i added a trace in the debug callback that gives me this:

i will now try with another version of libcurl as it seems
to me there really is a problem (or perhaps i'm going
slightly mad...)
thanks for your immediate answer, by the way.

GET /gestSmsgagn/sequ_audio/entree.php4

Both my test versions did fine. curl 7.11.1 and 7.14.0-CVS.

It just works!

No, i just can't figure it out unless a relative PATH in the
location header instead of an absolute uri leads to this
problem?
for a url, you can test at
http://portal.jetmultimedia.fr/gestSmsgagn/index_audio.php4?CALLEDNUMBER=%220825105010%22&CMPT%5fAI=2&%5f%5fTIMESLOT%5f%5f=30&%5f%5fDTIDEVICE%5f%5f=dtiB1T11
but it is perhaps not reachable from public. tell me, i'll
try to put it to another place.

for the thrid point, yes it's a strange behaviour; the
return code as retrieve by the CURLINFO_RESPONSE_CODE is
302. the CURLCODE returned by the easy_perform is
CURLE_URL_MALFORMAT. the effective uri as retrived by
CURLINFO_EFFECTIVE_URL is "/sequ_audio/entree.php4" with the
beginning slash.

We have more than 25 tests cases using Location: without
problems. Can you figure out what makes this special?

Can you provide us with a public URL that responds with a
Location: that causes this problem?

You say libcurl returns error CURLE_URL_MALFORMAT and in the
next sentense you say "the effective uri becomes...". What
do you mean?
