    There are a couple of solutions to this problem that I've seen. I don't
    recall all the vendors and all the products so forgive me. But I'll give
    you a dump of what I know.
    
    First, some IDS's (and this is where I forget the vendors) allow you to
    specify the private key that is used to encrypt the https data. With
    this in hand, the IDS is able to eavesdrop on the communication flowing
    by. Thats why its so important to keep those private keys private :-) If
    other people know what they are then they can snoop in on the
    communication.
    
    Second, you can use an SSL terminator. There are many vendors who have
    products that do this, some of them are simply SSL terminators and some
    of them include other features such as load balancing as part of the
    package. If you place the IDS on the non encrypted side of the SSL
    terminator you are free to look at the HTTP traffic as it flows by as it
    is all unencrypted.
