Abstract
A shortened identifier, such as a shortened URL, is used to access data, a service, and/or another resource that is associated with a full identifier, such as a full URL. In an exemplary embodiment, a hash key is generated from the full URL and included with a domain identifier to form a shortened URL. Other codes can also be included in the shortened URL. The shortened URL can be included in a message, page, and/or other data element that is generally too small for the full URL. When received from a client, a property code, a user ID, and/or other data is used to locate one or more full URLs. A selected hash function is applied to the full URLs to generate a table of hash keys. If a match exists with the hash key from the shortened URL, the resource is accessed at the corresponding full URL.
