Abstract
This invention discloses the cache content protocol for a content data delivery system. The cache content protocol defines a one-row table whose fields comprise three parts: content header, which includes provider ID, application type ID, category ID, and expiration time; extra criteria header, which includes extra criteria field count, criteria field IDs, and content cache record count; and criteria fields and actual data records, in which each record contains extra criteria fields, and respective actual content data, and the number of records is equal to the said content cache record count. Due to this arrangement, the cache content can be indexed by the following fields: provider ID, application type ID, category ID, and extra criteria fields.
