  • Methods and apparatus for web content transformation and delivery
    Patent number: 8086756
    Abstract: In a client, a system receives a set of transformation functions for use in transforming a first content, requests the first content from a gateway, and receives the first content from the gateway, including an invocation of at least one transformation function maintained on the client. The system invokes the at least one transformation function to transform the first content to access a second content on the server. In a gateway communicating with a server, a system transmits a set of transformation functions to at least one client for use in transforming a first content, receives a request from at least one client for the first content residing on the server, rewrites the first content to include the invocation of at least one transformation function maintained on the client, and transmits the first content including the invocation of at the least one transformation function maintained on the client.

  • Method for network discovery using name servers
    Patent number: 7165116
    Abstract: The invention provides a method and a system for associating the IP address of a client within a computer network with the address of the client's local domain name system (LDNS) server (“network discovery” function), and may furthermore use this association to provide such functions as network proximity analysis and load balancing. When a client's LDNS server queries the authoritative DNS (ADNS) server about an IP address of an application server, a name server monitor (NSM) of that ADNS server returns an IP address of an application server monitor (ASM) of the appropriate application server, instead of the address of the server itself, and records the IP address of the querying LDNS server, the ASM address returned, and a timestamp. When the ASM of the application server receives a request for web content from the client, it records the IP address of the client and a timestamp, with possibly other pertinent information (round-trip time, bandwidth estimate, etc.
