Abstract: An apparatus and a method for requesting data from a server over an HTTP connection. In one embodiment, a client reads a portion of a random access file from the server via the HTTP connection. The client requests for a limited amount of data at another location in the file on the same HTTP connection. The client receives the limited amount of data from the server on the same HTTP connection and reads the limited amount of data. The client requests for an additional limited amount of data at another location in the file on the same HTTP connection. The size of the additional limited amount of data is exponentially greater than the size of the limited amount of data. In another embodiment, the client requests for an additional limited amount of data at another location in the file on the same HTTP connection prior to finishing reading the limited amount of data.

Abstract: An apparatus and a method for requesting data from a server. In one embodiment, a client opens a first HTTP connection and a second HTTP connection with the server. The client requests for data from a random access file from the server with the first HTTP connection. The client receives and reads the data while maintaining the second HTTP connection open. The client requests for additional data at another location in the file on the second HTTP connection. The client maintains the second HTTP connection by occasionally sending requests to the server on the second HTTP connection.

Abstract: A method and apparatus that manages transactions during a data migration. The transfer of data from an old database to a new database is structured as a set of small transactions. The transactions can be structured in a hierarchy of dependent transactions such that the transactions are nested or similarly hierarchical. A migration manager includes a set of transaction management methods or processes that enable the processing of the nested transactions thereby providing a higher level of granularity in transaction size and providing the ability to rollback small individual transactions as well as affected related transactions. The transaction management methods and processes manage a set of queues that are utilized by the migration manager to generate and execute the nested transactions.

Abstract: A method and apparatus for transactions during a data migration. The transfer of data from an old database to a new database is structured as a set of small transactions. The transactions can be structured in a hierarchy of dependent transactions such that the transactions are nested or similarly hierarchical. A migration manager includes a set of data conversion methods or processes that enable the conversion of data from a format of an old database to that of a new database. The conversion process generates the nested transactions to resolve dependencies between records such as primary and foreign keys. The method and system provides a higher level of granularity in transaction size, providing the ability to transfer records individually and resolve the dependencies in such transactions without requiring a large mapping of an entire data set in the old database to an organization in the new database.

Abstract: A method and system for generating identity certificates. The method may include receiving a user login at a network appliance, determining that the network appliance is not initialized, and generating a provisionally unique identifier from the network appliance for identifying the network appliance. The method may include generating a certificate signing request (CSR) and sending the CSR, the provisionally unique identifier, and information about the user login to a service provider. Upon receiving a signed certificate from the service provider at the network appliance, the network appliance is initialized using the received signed certificate.

Abstract: A method and system for generating identity certificates. The method may include receiving a user login at a network appliance, determining that the network appliance is not initialized, and requesting and receiving a unique identifier from a service provider, where the unique identifier is used for identifying the network appliance. The method may include generating a certificate signing request (CSR) and sending the CSR with the unique identifier to the service provider. Upon receiving a signed certificate from the service provider at the network appliance, the network appliance is initialized using the received signed certificate.

Abstract: A system and method for filtering messages to identify spam. A Uniform Resource Locator (URL) is identified in a message, and information is fetched from the site designated by the URL. The fetched information is analyzed to determine if the message that includes the URL is spam. If the message is spam, then a message filtering action is performed, such as deleting the message, displaying the message to the recipient with a flag, and sending the message to a third party.
