Dear Paddock:
Per your advise, I downloaded Fiddler2 and started to use it. I had no problem run
1) Flex Builder, click bin\debug\index.html
2) Flex Builder, click bin\release\index.html
w/ Result 200 in Fiddler's Window.
For case:
IE: file:///C:/Users/.../Flex%20Builder%203/Flexviewer1.3/bin-debug/index.html (where the Flexviewer1.3 project
is in C:/Users/.../Flex%20Builder%203/), the map display well but no item displays in Fiddler window.
For other cases:
IE: file:///C:/Users/.../Flex%20Builder%203/Flexviewer1.3/bin-release/index.html
of IE: file:///C:/OtherFolder/.../bin-debug/index.html
No map is displayed and no item displays in Fiddler window.
Thanks for your attention.
