When a Web-browser user employs a hyperlink, a Web-information manager
makes a log entry that includes the URL of the Web page containing the
hyperlink and also lists the URL of the target Web page, to which the
hyperlink refers. When the user requests that a Web page be captured for
later use, the Web-information manager uses the log to find the page at
the root of the hyperlink chain that led to that page. It then determines
from the root page's URL whether the root page is a search-result page.
If it is, the Web-information manager infers the search specification
from that URL and associates it with the page to be captured.
