  • 4.7.0

Retrieves the closest matching site object by its domain and path.

This will not necessarily return an exact match for a domain and path. Instead, it breaks the domain and path into pieces that are then used to match the closest possibility from a query. The intent of this method is to match a site object during bootstrap for a requested site address
