I was not clear, my fault.

The site is possess many folders :
<http://www.example.com/folder1.page_name1.ashx>
<http://www.example.com/folder1.page_name2.ashx>
and
<http://www.example.com/folder2.page_name1.ashx>
<http://www.example.com/folder2.page_name2.ashx>

I'd like to mirror "folder1.*" only.
If I take you example should it be :
-* +www.example.com/folder1.*
?
Thank for you time and answers :)
