Hi and thx for your response

I have succeed to download a protected part of a forum under the vBulletin
plateform this way:

1. For exemple, go to the memberlist page and catch the url while connecting
(I went on Bulletin.com/forum/memberlist.php)

2. Project option:
        -filter:   -*
                   +*member*
        -no robots
        -Copy your exact user agent in the browser section (I had look in the
hts-post0 file for my user agent)

3. Copy the cookie of your browser in your project folder.

4. Start the projet

This way, I can download the memberlist part. I tried a lot of thing
before...like starting the mirroring from the index.php page, but it seems
that httrack lost the connection when it "change section to section in the
forum". It's like if changing from the "Post" section to the Member" section
during the scan make httrack lost the connection, even if it still on the same
site. So, asking httrack to stay in the same section seems to work (-* and
+*member*)... My understanding of this behavior of httrack can be wrong, so
what I just said can be false... I will try some others things soon to see if
I can download a bigger part of the forum at the same time and not only a
section.

I also tried to download a protected part of the forum  with wGet without
success.

I first connect to the site to "activate" my session cookie and I enter this
command (on linux):

wget --html-extension --keep-session-cookies --relative
--load-cookies=/root/.mozilla/firefox/dzipmeoa.default/cookies.txt 
<http://www.vbulletin.com/forum/memberlist.php>

I'm not very familiar with wGet... does someone have an idea?

Thx for your help
