|
||
|
|
-- null when the page names none; a client is credited with the link's host
|

|
|
-- only when dinners.SourceOf finds the link safe to show. Before this, a

|
-- page naming no site was stored under the host of the URL it was served
|

|
|
-- from, which may carry a personal token, and nothing recorded which a

|
-- stored name was. A stored name that could be a host — a dotted host name
|
||
|
|
-- or an IP address, spelled only in host characters — is cleared here, so
|

|
|
-- every stored name is one a page gave. A site that names itself as a
|

|
|
-- domain, such as "Food.com", loses its stored name with them until its
|

|
-- recipe is fetched again, and is credited by its link's host meanwhile

-- when the link is safe.
