Mhm, my mistake - I've thought about refering sites, not about aliases.
Sorry, I corrected.
Example: often, "two" URLs (eg: http://www.site.com and http://site.com) point to the same site.
Could PMV count this two adresses as one?
edit: I thought about referers, not about site url.
I'm not sure what you mean, but PMV already has something like that
