    Hi..
    
    [This has been around in perl scripts for a while now..]
    
    IIS throws a different (predictable) Content-Length value based on its
    applied Service pack level.
    
    The attached .nasl makes a guess @ remote IIS sp-version based on the
    returned Content Length. (This only tested on English versions..)
    (Thanks muchly to robat_private for most of the signatures / initial
    .pl)
