A method, system, and computer program product for aiding a user in navigating documents containing hyperlinks is provided. In one embodiment, the system retrieves, in response to a user request, a document from a network location. The system parses the document for hyperlinks and responsive to detecting a hyperlink, sends a request for at least a portion of the secondary document associated with the hyperlinks to a server. The portion contains information sufficient to determine relevance of the secondary document to the user. The system then receives the information from the server and compares the information within the portion of the secondary document to reader preferences. Based on the results of the comparison of the information with the reader preferences, the system modifies the appearance of the hyperlink. If the system determines that the secondary document is highly relevant to the user, the system may also prefetch the secondary document and store it in a read ahead cache to speed up browsing for the user.
