1. A method for prefetching content from incoming messages and managing caching at a computer, said method comprising:

  • scanning, by a processor of the computer, an incoming message;

    detecting, by the processor, one or more resource links in the scanned incoming message;

    in response to said detecting the one or more resource links in the scanned incoming message, determining, by the processor, that users of the computer are likely to request a content of the detected one or more resource links, said determining, that the users are likely to request the content of the detected one or more resource links, being based at least on a type of the one or more detected resource links and a type of network to which the computer is connected;

    in response to said determining that users of the computer are likely to request a content of the detected one or more resource links, ascertaining, by the processor, whether or not the content of the one or more resource links has been previously cached at the computer as a previously cached content of the one or more resource links;

    if said ascertaining ascertains that the content of the one or more resource links has not been previously cached at the computer, then in response to said ascertaining, caching, at the computer by the processor, the content of the detected one or more resource links;

    if said ascertaining ascertains that the content of the one or more resource links has been previously cached at the computer, then in response to said ascertaining, said processor making a determination of whether or not the previously cached content of the one or more resource links is current relative to the content of the detected one or more resource links;

    if said determination is that the previously cached content of the one or more resource links is not current relative to the content of the detected one or more resource links, then in response to said determination, caching, at the computer by the processor, the content of the detected one or more resource links; and

    if said determination is that the previously cached content of the one or more resource links is current relative to the content of the detected one or more resource links, then in response to said determination, not caching, at the computer by the processor, the content of the detected one or more resource links,wherein the incoming message is an email message sent by a sender, and wherein the one or more resource links are in the sender'"'"'s email signature in the email message, andwherein said determining that users of the computer are likely to request the content of the detected one or more resource links is further based on determining that the detected one or more resource links are pointing to one or more files and are not pointing to a corporate website.
