摘要： Described are methods and systems for managing the connections between a client, an intermediary appliance and a server, so that asynchronous messages can be transmitted over HTTP from the server to a client. When a connection is established between a client and an intermediary, and the intermediary and a server to establish a logical client-server connection, that logical client-server connection is labeled and not maintained, while the connection between the client and the intermediary is maintained. Messages generated by the server and destined for the client are transmitted to the intermediary along with the connection label. The intermediary can then use the connection label to determine which client should receive the message.

摘要： In a method and appliance for using a dynamic response time to determine responsiveness of one or more network services on a server, a monitor determines a response time for each of one or more network services. The monitor establishes an average response time based on the determined response time for each of the one or more network services. The monitor associates with the established average response time a predetermined threshold for which the response time of the one or more network services may deviate from the average response time and maintain an indication of responsiveness. The monitor monitors the response time of the one or more network services to one or more requests. The monitor determines that the response time of the one or more network services deviates from the average response time by the predetermined threshold. The monitor indicates that the one or more network services are unavailable.

摘要： In a method and appliance for determining responsiveness of a service via a particular protocol, a device intermediary to a plurality of clients and a plurality of services determines response times from each of a plurality of services to respond to requests via a first type of protocol of a plurality of protocols. The device calculates an average response time for the first type of protocol from each of the response times of the plurality of services. The device establishes a predetermined threshold for which a response time of a service for the first type of protocol may deviate from the average response time. The device identifies a service as available responsive to determining that a deviation of the response time of the service from the average response falls within the predetermined threshold.

摘要： The present invention provides maintains site persistence in a hierarchical Global Server Load Balancing (GSLB) deployment. Via configuration of GSLB services locally and remotely on each of the GSLB appliances and LB appliances at a site, a site appliance identifies and associates requests from the GSLB with the site. Furthermore, the site appliance may receive a GSLB cookie with the client request and confirms the request is from the expected GSLB in the site hierarchy. When the load balancers receives a response from a server, the appliance may include the GSLB cookie with the response back to the client. The appliance may also include an LB cookie to identify the server selected by the LB. When the client sends another request, the request may include the GSLB and LB cookie.
