Controls the behavior of files fetched by Network Links.

Name:	You can control the name of the network link from the server, so that changes made to the name on the user side are overridden by the server.
Expires:	You can specify a date/time at which the link should be refreshed. This specification takes effect only for Time Based Refresh in the Network Links who has a value of onExpire.
Min. refresh (sec.):	Specified in seconds, it is the minimum allowed time between fetches of the file. This parameter allows servers to throttle fetches of a particular file and to tailor refresh rates to the expected rate of change to the data. For example, a user might set a link refresh to 5 seconds, but you could set your minimum refresh period to 3600 to limit refresh updates to once every hour.
Cookie:	Use this element to append a string to the URL query on the next refresh of the network link. You can use this data in your script to provide more intelligent handling on the server side, including version querying and conditional file delivery.
Message:	You can deliver a pop-up message, such as usage guidelines for your network link. The message appears when the network link is first loaded into Google Earth, or when it is changed in the network link control.
Snippet:	You can control the snippet for the network link from the server, so that changes made to the snippet on the user side are overridden by the server. The Snippet has a max lines attribute, an integer that specifies the maximum number of lines to display.
Description:	You can control the description of the network link from the server so that changes made to the description on the user side are overridden by the server.
