You could use the CryptoAPI to digitally 'sign' the ASP page, you would
have to store the signature key in a file and use a custom DLL to validate
it, but it would prevent any changes to the ASP code without resigning the
file. It would not however prevent people from viewing the ASP code if
they have server access. That's not the nature of what ASP is about of
course.

>I am in the same boat. I have some things to install on a 3rd-party ISP's site, and I really have no control over their admins; I'd hate for someone to grab my source and re-sell it elsewhere. With VFP I have a few coding tricks to at least stamp things "mine", but it would be great to do the same for ASP....

>>The problem is that what I'm distributing is a web server / database application. That is, the Active Server Page scripts are integrated with a VFP application, all running on my customer's machine. I don't want my customers to be able to read the ASP scripts. I just want them to be able to use them, and maybe influence behavior of the scripts by providing a modifiable server-side include file.
