Patent number: 9648043Abstract: Embodiments of the invention provide techniques for processing messages transmitted between computer networks. Messages, such as requests from client devices for web services and other web content may be transmitted between multiple computer networks. Intermediary devices or applications such as proxy servers may receive, process, and transmit the messages between the communication endpoints. In some embodiments, a reverse proxy server may be configured to dynamically generate Representational State Transfer (REST) services and REST resources within the reverse proxy server. The REST services and REST resources within the reverse proxy server may handle incoming requests from client devices and invoke backend web services, thereby allowing design abstraction and/or enforcement of various security policies on the reverse proxy server.Type: GrantFiled: April 25, 2015Date of Patent: May 9, 2017Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Nitin Handa, Prakash Yamuna

Patent number: 9055068Abstract: Framework for conditionally attaching web service policies to a policy subject (e.g., a web service client or service endpoint) at subject runtime. In one set of embodiments, a constraint expression can be defined that specifies one or more runtime conditions under which a policy should be attached to a policy subject. The constraint expression can be associated with the policy and the policy subject via policy attachment metadata. The constraint expression can then be evaluated at runtime of the policy subject to determine whether attachment of the policy to the policy subject should occur. If the evaluation indicates that the policy should be attached, the attached policy can be processed at the policy subject (e.g., enforced or advertised) as appropriate. Using these techniques, the policy subject can be configured to dynamically exhibit different behaviors based on its runtime context.Type: GrantFiled: August 28, 2012Date of Patent: June 9, 2015Assignee: Oracle International CorporationInventors: Jeffrey Jason Bryan, Nickolas Kavantzas, Prakash Yamuna, Cecilia Zhao

Patent number: 9021055Abstract: Arrangements for enforcing a nonconforming web service policy document are presented. A request for a web service policy document may be received by a web service. A conforming web service policy document may be generated using the nonconforming web service policy document. The nonconforming web service policy document may comprise one or more functions unsupported by the web service description language. The conforming web service policy document may be transmitted to the web service client. The nonconforming web service policy document may be enforced by the web service, wherein the functions that are unsupported by the web service description language standard modifies enforcement of the web service policy document by the web service computer system. The conforming web service policy document may comprise sufficient information for the web service client computer system to comply with the nonconforming web service policy document.Type: GrantFiled: May 31, 2011Date of Patent: April 28, 2015Assignee: Oracle International CorporationInventors: Nickolas Kavantzas, Prakash Yamuna
