I'm trying to mirror:

www.w3schools.com/html/html_examples.asp

In this page there are several links to pages all of the 
same type. For example, one link leads to 

<http://www.w3schools.com/html/tryit.asp?filename=tryhtml_iframe> 

Once opened the page you can find a code like this:

<frame frameborder="1" name="edit"
src="tryit_edit.asp?filename=tryhtml_formattingch&referer=http://www.w3schools.c
om/html/html_examples.asp" scrolling="auto">

<frame name="view" src="tryit_view.asp?filename=tryhtml_formattingch">

Which should generate two files: tryit_edit (in the first 
<frame> tag) and tryit_view (in the second).

If I try to mirror www.w3schools.com/html/html_examples.asp 
all the files like tryit_edit-xx.html are not generated 
(but with tryit_view-xx.html all works fine), whereas if I 
mirror directly
<http://www.w3schools.com/html/tryit.asp?filename=tryhtml_iframe> both files are
catched. There is a 
way to make the mirror from html_examples.asp working? (I'm 
using - with satisfaction - WinHTTrack 2.02b) 
Thank you in advance.
