Abstract: The present invention provides a configuration information push method and device. The method includes: obtaining a polling request sent by a client; determining whether configuration information of configuration items in the polling request is consistent with current configuration information of corresponding local configuration items, if yes, keeping a short connection to the client; monitoring the configuration information of the corresponding local configuration items, and if, in a duration of the short connection, current configuration information of at least one target configuration item in the local configuration items is inconsistent with configuration information of a corresponding configuration item in the polling request, pushing the current configuration information of the target configuration item to the client, so that the client updates a configuration of a corresponding target configuration item to the current configuration information.
