My first guess would be that your rendered page has image/script elements
that are referenced using relative urls:
<img src="assets/img.gif"/> which would be translated to
"..../productdetail/assets/img.gif" in the browser request.
My second guess is that the link you clicked on isn't what you think, but
that seems less likely.
