DYNAMICALLY INCORPORATING UPDATES TO ACTIVE CONFIGURATION INFORMATION

A method, system, and computer-readable medium is described for dynamically incorporating updates to configuration information in active use and for providing access to the updated configuration information as appropriate. In some situations, the configuration information being dynamically updated is various types of Domain Name System (DNS) information, including DNS resource records, configuration records, whois records, and delegation records. Depending on the manner in which configuration information is stored and used by a computer, that configuration information can be dynamically updated in different manners. When configuration information is stored in multiple data files and is also cached in memory, an update file can be maintained to indicate the stored data files that have been updated more recently than their corresponding cached information. Alternately, an update file can be maintained for configuration information stored using other storage schemes such as a database, and data structures other than a file can be used to hold the update information.
