First Claim
1. A relay device which connects a local area network to a wide area network, the relay device comprising:
- an identifier checker, configured to determine whether or not an identifier uniquely indicating an available resource through the wide area network is included in an email that the local area network receives from the wide area network, and register the identifier in a database when the identifier is included; and
a redirect section, configured to determine whether or not an identifier indicating a resource available through the wide area network is registered in the database in response to detection of access from a terminal device within the local area network to the available resource, display a screen inquiring whether to perform access in the terminal device when the identifier is registered, and relay the access when a reply allowing the access is obtained.
