What i mean is that , say our content is in a data base and is accessed as

/directory.aspx
/directory.aspx?page=1
/directory.aspx?page=2
/directory.aspx?page=3

The sitemap generator only lists

/directory.aspx

Is this supposed to be the standard or do i need a new
sitemap generator,

I know people have had issues with sitemap generators so I imagine the solution has been found

Cheers
