 |I guess our problem is easy to solve if I would know how to do it right... 
 |The normal internet access in our company takes place about a proxy server 
 |with user login and password. This proxy server is located at a remote 
 |data center to which we have no access. Now some of our users must have 
 |access to a special https-site ( This 
 |site uses a Java applet which is automatically downloaded if the user 
 |rights for the proxy server allow it. But for security reasons most of our 
 |users are not allowed to download software from the internet and so we 
 |have to look for another solution.
 |This is where delegate was brought into play. Our idea is to use a special 
 |proxy user with download rights on our delegate server to connect to the 
 |data center proxy server and from there access the https-site. Our users 
 |would connect with the delegate proxy server and could not exploit the 
 |additional rights of the proxy user because the access is restricted to 
 |this special site.

So you are not bypassing the upstream proxy but automatically passing it.

 |Is that possible with delegate and if yes how? Right now we had no success

 |ideas. Maybe someone with a little more experience can help us? :-)
 |Our actual configuration:
 |        ADMIN="$MAIL" \
 |        SERVER=http \
 |        MYAUTH="user:password" \
 |        $PORT \
 |        MOUNT="/**" \
 |        DGROOT="$DIR" \
 |        PERMIT="$PERMIT" \
 |        HTTPCONF="ver:1.1"

You need to specify inserting a SSL filter into the connection with ther
server as this:
