It won't be. If this was posted to Bugtraq I would expect the next event
to occur would be hell freezing over and the end of the world.

I can. It is called normal dumb browser behaviour, not big webserver
security hole. You want a hole, dig one, you are going nowhere with this.

Why not try it? You'd see that it doesn't work. The only time appending
characters to the end of an ASP would download it would be if the person
was running IIS 4.0 and the ASP resided on a mapped drive and the admin
didn't install a patch from way back in 98. I doubt that is the case
here. The reason the file was downloaded is because netscape is
stupid. End of story. IE didn't download the file not because it ignored
the slash...when you add a slash it assumes you want the directory
/index.html/ which could be a valid directory...the webserver however did
remove the slash.
