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： The present invention provides systems and methods for maintaining 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. With this information, the GSLB and LB appliance may maintain site persistence for the client as well as server persistence at the site.

摘要： The present invention provides a system and a method for global server load balancing of a plurality of sites based on a number of Secure Socket Layer Virtual Private Network (SSL VPN) users. The SSL VPN users may access servers at each of the plurality of sites. A global server load balancing virtual server (GSLB) may receive a request to access a server. The GSLB virtual server may load balance a plurality of sites wherein each of the plurality of sites may further comprising a load balancing virtual server load balancing users accessing the server accessing servers via an SSL VPN session. GSLB may receive from a first load balancing virtual server at a first site, a first number of current SSL VPN users accessing servers from the first site via SSL VPN sessions. The GSLB may also receive from a second load balancing virtual server at a second site, a second number of current SSL VPN users of the users accessing servers from the second site via SSL VPN sessions. GSLB may determine to forward the request to one of the first load balancing virtual server of the first site or the second load balancing virtual server of the second site by load balancing SSL VPN users across the plurality of sites based on the first number of current SSL VPN users and the second number of current SSL VPN users.

摘要： The present invention is directed towards systems and methods for dynamically redirecting on a client communications of the client with a server to bypass an intermediary that is determined to be unavailable for such communications. An acceleration program on the client establishes a transport layer connection between the client and server, and intercepts communications of the client to the server. The transport layer connection may be established via an intermediary, such as a gateway, proxy or appliance. If the client-side acceleration program determines the intermediary is not available for communicating by the client to the server, the acceleration program automatically establishes a second transport layer connection to the server in order to bypass the intermediary. The acceleration program then transmits the intercepted communications of the client via the second transport layer connection to the server. The acceleration program may automatically redirect intercepted communications of the client to the server transparently to any user or application of the client.
