Currently, if we go to [[Special:Book]] using the secure server, each of the items in the collection list has a lock icon [1] beside the icon [2] which points to the page corresponding to the item.

Since the lock icon is inserted by the CSS selector
div#content a[href^="https://"]
, I think the link should be changed to a relative such as
/wikibooks/en/wiki/Test

instead of a full url like
https://secure.wikimedia.org/wikibooks/en/wiki/Test
