ASP.net uses a server-side script, which is interpreted and turned into HTML on the server. After this the finished HTML is sent to the browser.

The bits that look like this to be specific.

CODE

<%
...
%>

You will never see those when you view source over a server. Unless something is wrong.

Yes, the ASP code is within those signs. And that's why you don't see it over the server. The server interprets the ASP and replaces it with what the code instructs it do do. What's sent to the browser is always plain HTML (and CSS and JavaScript). The ASP is all gone. Another programming language that can be embedded in HTML like this is PHP. It's called pre processing. Languages like for example Perl work differently. A Perl script can be called from a HTML page but you can't embed snips of programming like this.

How is Perl different, and how is that done?

[pandy]

I meant in the sense that you can't embed actual programs/scipts in a HTML page and have the server parse the page for that as with PHP and ASP. It isn't a preprocessor (if that's even a term). Instead the script must be called, like when submitting a form. The result can be that the script generates a whole now page with the desired result.
