My starting point is 
1) <rootURL>/Index.pasp
On this page I have links to
2) <rootURL>/TOC.pasp
On this there are links to 
3) <rootURL>/Download.asp?ProductID=
The last link is downloading PDF file in browser.

I like to get all the pdf's on this site.

I tried with the following scan rules but I could not go to 
the 3) link at all
<rootURL> -* + <rootURL>/TOC.pasp* + <rootURL>/Download.asp*

Can you advice me the best Scan rule to get all the PDF's ?Thank you,
Ravi
