I am using Nessus 3.0.4 on Win XP. I can configure it scan the

Can you point to specific things that Nessus that you feel Nessus has
missed?

As I said, the Web site has thousands of pages. A thorough scan would
not finish so fast. 

Are these pages written using a scripting language such as PHP
or ASP rather than just static pages?

Yes, they are. Most of them have .html extensions, but have PHP inserts.
This is an additional interesting question: how can Nessus check for PHP
vulnerabilities if PHP code never leaves the server? 

And if so, are they linked in from
the initial page or in well-known directories?

Yes. May be, not all of them, but most.

Why? That plugin generally won't report anything; instead, it updates
the KB with information found with entries such as:

   www/80/content/extensions/html

Because I read in it's description that it creates a local mirror of the
site. I don't see this happening.


The question is, how do I enable thorough tests?

If you're using the Nessus 3 client for Windows itself, you do this by
editing a new policy and selecting "Thorough tests" under the
"General"
settings tab.

Sorry, there is nothing about "Thorough tests" there, nor under other
tabs. The white paper you refer to below also mentions existence of
"Thorough tests" just a few lines away from a screen cap that shows that
there are no "Thorough tests" there.
 
I found a couple of books describing Nessus, but they talk about
Nessus
2. The new Nessus 3 interface is intuitive, but not well documented.

Have you look at the white papers here:

   http://www.nessus.org/documentation/

Included are two user guides for Nessus 3.0.

Sure, I've read these documents. They did not answer my questions.
