Abstract
A server system provides responsive content to a user when a request for an invalid URL is received. The server system may implement multiple rescue strategies for attempting to rescue the invalid URL. One such rescue strategy involves repairing the URL by correcting for encoding errors. Another rescue strategy involves determining that the URL contains an obsolete or outdated item identifier (e.g., product identifier) that renders the URL invalid, and returning information regarding one or more related items to the user. Another rescue strategy involves mining the invalid URL for one or more text strings reflective of the type of content desired, and then using the one or more text strings to execute a keyword search to identify content to provide to the user. The various rescue strategies may be attempted in sequence according to a hierarchy.
