Why URL '/index.html' and '/' are indicated in the 'Requests per page' section? How is the homepage indicated?
Both '/index.html' and '/' indicate the homepage. This is because the browsers read the homepage address in different ways.
It is possible to avoid this by naming that page with the parameter PAG= as shown in the guide Dynamic page option. This action performed in the 'Requests per page' report will allow you to display the name assigned to the homepage instead of '/index' and '/'.
