Hi Daniel,
 
FYI: I try to simulate the navigation within a site in order to post data
on several forms.
        First problem: send the username and password to get the login page.

=> First of all, when I test CURLOPT_COOKIEFILE, nothing seems to be written
in my cookie.txt. Is there
something wrong in this code (my username and password are within
$LOGINURL):

$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEFILE, 0);
curl_setopt($ch, CURLOPT_COOKIEJAR, "C:\tmp\cookie.txt");
curl_setopt($ch, CURLOPT_URL,$LOGINURL);
curl_exec ($ch);
curl_close ($ch);

=> Concerning CURLOPT_FOLLOWLOCATION, I'm not sure to well understand how I
could use it. Indeed I tried
to make a simple request on another site (my mailbox) with my username and
password and it worked well, I got
the page after login, I didn't even need to use CURLOPT_FOLLOWLOCATION!
The problem is that the servlet from my work site doesn't give directly the
name of the login page as on my
mailbox, there is previously several requests:
 
.../servlet/oapdev?page=oap_fset_after_login.jsp
and then only:
.../eng/oap_fset_after_login.jsp
and then the 3 frames of the "after login page"...

The frames management is not a problem, all I have to do is to put the right
cookie in each request header.
CURLOPT_COOKIEJAR should be appropriate for this kind of work, if I succeed
in using it...;-)
 
=> Another little question:
Is it possible to make several request in only one curl_exec()? I'm mean
doing each request
with the previous cookie, to simulate a navigation until the right page. The
following code is surely wrong,
but you get the idea...;-)

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"$LOGINURL");
curl_setopt($ch, CURLOPT_COOKIEFILE, 0);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_URL,".../page1.jsp");
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_URL,".../page2.jsp");
curl_exec ($ch);
curl_close ($ch);

Besides is the code executed in the same order as the written code? In other
words, is the curl_setopts order important?

Thanks a lot.

No? Usually sites pass a cookie back and a Location: header to the page it
wants you to do to after the login.

Well, unfortunalely, we have different issues to deal with here. libcurl
itself allows pretty flexible ways to solve this, but AFAIK the PHP/CURL
module is not offering access to all those.

If there is a Location returned from the login post, then use FOLLOWLOCATION
and have COOKIEFILE set to a non-existing file (makes it read no cookies by
default but parse returened one). When following the Location, it'll use the
proper cookies in the subsequent request.

You should probably consider using the COOKIEJAR option to have the cookies
stored in a cookie file when the handle is closed, and then set that file
with COOKIEFILE on following requests, which makes them use the proper
cookies automaticly.

CURLOPT_COOKIEJAR saves cookies in a file.
CURLOPT_COOKIEFILE reads cookies from a file
CURLOPT_COOKIE sets a cookie in a request.

Oh sure. Been done a million times.
