The replies still stand.  The only way the unprocessed
asp page will make it to the client is if there is a
"fatal" flaw/misconfiguration of the IIS server. 
Otherwise all request for the file via the http web
server will be processed by the asp dll engine. 
However if you request the file via ftp or something
of the sort then yes you will get the unprocesses code
back from the server.

Well, it seems I have not been very shape in my last

side, and not in the client's browser (it will just
receive the results of the scriting).

But if a client requests "toto.asp", despite of if
it will receive the "toto.asp" WITHOUT the ASP
scripts, the server has a "full toto.asp" WITH the
asp scripts. So my question was: as the server has
in his directory this "full toto.asp", is there a
way to get the "full toto.asp" from the server?

Martin,

 I am not quite sure what you are asking? 

      Are you asking about 'Classic' asp? Classic ASP
code is intertwined with HTML in a .ASP file. It is
executed server side. The end user cannot 'see' the
ASP code, even if they look at the source because
the code is executed at run time and never sent to
the browser. So long as your server and the original
code is secure then end users can't see the code.

      Are you talking about client-side
VBScript/JavaScript that runs in the browser? If so,
it is very hard to hide that from the browser
because the browser needs to be able to read it to
execute the code.

      Or, are you talking about an ASP application that
you plan on selling/deploying and putting on a
clients' server. And not wanting them to get access
to the code? If this is the case, and you are using
ASP.NET you can use the code obfuscator to blur the
code. If you're using classic ASP, I believe you are
S.O.O.L.

HTH,
--Yonah

Subject: ASP security in HTML pages


Hi list,

I have been googling around to know how secure can
be ASP code, and I found what follows:
- For a newbee, impossible to get the asp scripts
inserted in an HTML page as they are not displayed
in the client's browser,
- Instead of just letting the ASP code in the HTML
pages, we can create some DLLs for example, but a
not-to-bad skilled hacker can get and reverse them.

So, my question to you, skilled-people :) is: is
there a way to get the asp scripts in a page the
server does not send when a client's request
arrives? There should be a way to ^perform that, but
how tough is it?

Thanks in advance, folks!
