$20 paypal'd to the first person that can show me how to 
get winhtttrack to take a site that uses this forum 
software: 
<http://www.hardforum.com/index.php?s=35967cc484896840d8aa210122c919d7>  (its
called Vbulletin).

The problem I have is that the private forum I want to 
cache for offline browsing is password protected.  When I 
tell winhttrack to scan it (with all the pluses clicked, 
and cgi and php set to text/html in the mime types.

Thus everytime I try to copy the site, it just shows this: 
You are not logged in or you do not have permission to 
access this page. This could be due to one of several 
reasons: 
You are not logged in. Fill in the form at the bottom of 
this page and try again. 

You do not have permission to access the page that you were 
trying to. Are you trying to edit someone else's post or 
trying to access administrative features? Check that you 
are allowed to perform this action in the Forum Rules. 
If you are trying to post, the administrator may have 
disabled your account, or it may be awaiting activation. 

But when I go to the site with a normal new browser, It 
just works automaticly, with no loging in or anything.

I have also tried to use a username and password in the url 
username and password fields, it did not work.  I think its 
because it uses its own php to see whether you are logged 
in or not.
