A content file purge mechanism for a content delivery network (CDN) is described. A Web-enabled portal is used by CDN customers to enter purge requests securely. A purge request identifies one or more content files to be purged. The purge request is pushed over a secure link from the portal to a purge server, which validates purge requests from multiple CDN customers and batches the requests into an aggregate purge request. The aggregate purge request is pushed from the purge server to a set of staging servers. Periodically, CDN content servers poll the staging servers to determine whether an aggregate purge request exists. If so, the CDN content servers obtain the aggregate purge request and process the request to remove the identified content files from their local storage.

The entity for message interworking is also provided. Additionally, a message delivery report processing method and system are also provided.

A method and system and computer readable medium for: (1) the creation and representation of business rule definitions, (2) the creation and representation of enforcing rule handlers, (3) the creation and representation of a framework to check the existence of rules then, apply the appropriate handler, (4) and the distribution of the rule definitions and handlers to clients. The present invention defines a rule language and provides a framework that separates the definition of the rules, the enforcing handler, the system at which rules are generated and the system at which rules are enforced. Further, in one embodiment, the present invention uses standard XML notations to define rules and standard XSL and XSLT processing instructions to enforce rules. Using standard XML, XSL and SXLT allows clients to use off-the-shelf XML parser and XSL processors in lieu of developed code or rule based engines.

A method, system, and computer-readable medium for maintaining up-to-date, consistent backup copies of primary data that are immune to corruption even when security of the primary data is breached. Independent security domains are established for primary and secondary data, such that access to each security domain must be obtained independently of access to the other security domains. For example, a host computer system having access to data storage in the primary security domain does not have access to data storage in the secondary security domain, and vice versa. Changes to primary data are synchronously replicated over a tightly controlled replication link from primary data storage in the primary security domain to secondary data storage in the secondary security domain. A change to the data is completed in the primary security domain when an acknowledgement is received that the change to the data has been stored in secondary data storage.

The system comprises the cache servers, a cache client side and the cache clustering manager, wherein the cache servers are connected with the cache client side and the cache clustering manager through the network. The invention ensures the uniform distribution of the network flow among the cache nodes, optimizes the utilization rate of system resources, and solves the problems of ensuring data consistency and continuous availability of services.

Systems and methods facilitate information sharing among a plurality of member institutions. Each member is associated with a member number and a corresponding member profile. A member contributes its data relating to small business entities to an exchange repository upon becoming a member, and thereafter on a periodic basis. Each member is eligible to query against the exchange repository. However, a response to a member's inquiry is determined by a reciprocity due to the inquiring member. If a member contributes comprehensive information regarding small business entities in its portfolio, then the member receives comprehensive information relating to a small business entity that becomes a subject of its inquiry. If a member contributes minimal information regarding the small business entities in its portfolio, the member receives minimal information relating to a small business entity that becomes a subject of its inquiry, regardless of the amount of information available in the exchange repository. Each business entity regarding which information is stored in the exchange repository is associated with a business entity identifier. A business entity identifier associates a record file for the corresponding small business entity. The record file includes trade data of the small business, data relating to one or more principals of the small business entity, as well as data relating to one or more guarantors of the small business entity, as appropriate.

A system and method for generating language-translated versions of software include a parsing engine to scan original-language versions of software, and detect textual string or other expressions which may require translation for other countries or markets. After testing for prior translation, those strings may be converted to appropriate expressions in other languages, and for instance stored in paired-memory or other format. Users may download the original version of the software, and then install run-time, language-specific resources to tailor the software to their market or country. The run-time, language-specific resources may be or include resource-only dynamic link libraries (dlls). In embodiments the target language into which translation may be made may be automatically detected using the regional settings of the user's machine, or otherwise. Because translation resources for various sets of languages may be generated before the release of the original code, software products may be deployed in various markets and countries at the same time as the original code. Staggered release of localized versions of a software product in one country after the other is therefore not necessary, and software maintenance is made more efficient.
