It wasn't misconfiguration since the Website was working perfectly before that (for several months). My opinion (since FastHosts didn't give me access to the logs) is that the .Net framework somehow got corrupted. Comments from FastHost's support staff (in March 2004): "...The .Net Framework appeared to have become corrupted on the domain, after reinstalling the framework via the control panel, this resolved the issue. We can't guarantee this won't happen again and sadly it's not possible for me to find out the exact reason as to why this occured, however this is a very rare occurance and it is extremely unlikely the issue will reoccur..." And "... Personally, I have only seen this issue occur once in the past 8 months. In what respect do you require logs? You can see the standard logfiles for your site within the 'logfiles' folder on the domain's FTP, however no other logs are available. ..." I haven't had time to further investigate this since it would be very useful to understand the cause of the problem (although FastHosts have already seen this problem at least twice). Dinis

Fasthosts refused to give me more details about the circumstances around the event (like logs, open threads, debug information, etc...) so I was not able to find more information about what caused the problem in the first place.

Some examples: http://www.securityfocus.com/bid/2909/info/ http://www.microsoft.com/technet/security/bulletin/MS01-004.mspxhttp://www.netscreen.com/services/security/di_resource_center/threat_definit ions.jsp?id=91 As _Hacking Web Applications Exposed_ puts it: "With the track recordthatIIS has had in the source disclosure department, it's never a good ideatoassume that someone won't be able to view your source code" (55). It's sometimes suggested that scripters wrap database connectionstrings,encryption keys, and other sensitive information in COM objects to keep them private. Are there alternatives? What sorts of strategies do people usetokeep their script contents confidential?

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. ~Harrison --- Binoni_MARTIN <Benoni.MARTIN () libertis ga> wrote:Well, it seems I have not been very shape in my last posting. I know ASP code is executed on the server's 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?
