     Hi All,
        I don't know if there is a patch for this, or if this is already
     well known, but here it is. A simple workaround follows.

     Problem: Livewire Applications are downloadable. (Passwords are

     Platform: DEC UNIX 4.0D (possibly all Unixes/NT)

        Livewire applications are basically server-side Javascript
     applications that behave similiar to Active Server Pages. The main
     difference is that Livewire applications are compiled to a proprietary
     byte executable that contains all the pages in the application.
        These applications are generated with .web extensions. In their own
     example, the game hangman is accessed as
     http://www.myserver.com/hangman/ and the application is hangman.web.
     So accessing http://www.myserver.com/hangman/hangman.web will download
     the application to your browser.
        The second problem lies in the fact that all the pages are
     readable, and that database username/passwords are unencrypted, unless
     specifically encrypted in your application.
        The two problems combined can compromise security. This problem
     occurs regardless of Web directory permissions from a server level.

     Quick Workaround:
        Rename the .web application to something cryptic like G6r$79k9.web
     and make sure that the directory it's in isn't a document directory.

        I verified this problem on a few Internet sites, which leads to the
     question: If you verify a web security problem (remember 
.. at the end
     of Active Server Pages) is this technically illegal.
        If anyone knows if this problem has been fixes I'd really
     appreciate it.
