Claim:
A computer-implemented method for identifying previously-visited items in a search session, comprising: under the control of one or more computer systems configured with executable instructions, in response to a user request to display information related to a search for an item on a client computing device during a current search session, obtaining at least one item identifier associated with the item using a trusted script executing on the client computing device; determining whether the obtained item identifier matches any stored item identifier for a previous search session associated with the user; if the obtained item identifier matches a stored item identifier, providing the matched item identifier, time data associated with the matched item identifier, and a last visited resource identifier for the matched item to the trusted script; verifying the last visited resource identifier using the trusted script; and if the last visited resource identifier is verified, setting at least one property of a link to an item associated with the matched item identifier to indicate, when displayed, that the link is associated with a previously viewed item, wherein a link to a previously-viewed item is distinguished from other links displayed on the client computing device independent of whether a current resource identifier for the item is the same as the last visited resource identifier.
