A method of controlling data transfer between a first and a second computer network comprises parsing content description language received from the first computer network to determine tag information with the content description language. A completion decision is made based on the tag information. For one embodiment, the completion decision may include any of the following: full data transfer between the two network, partial data transfer between the two network, a deferred data transfer at a later time, or a cached data transfer. Restrictions based upon a user's age, a user's access right, cost, system resources, and time of day may also be employed to limit the transfer of data based upon the tag information.
