Transaction accelerator for client-server communication systems
View Patent ↗In a network having transaction acceleration, for an accelerated transaction, a client directs a request to a client-side transaction handler that forwards the request to a server-side transaction handler, which in turn provides the request, or a representation thereof, to a server for responding to the request. The server sends the response to the server-side transaction handler, which forwards the response to the client-side transaction handler, which in turn provides the response to the client.

in response to determining that the portion of the response data is not locally accessible to the first apparatus, the second apparatus modifying the response data to obtain modified response data, wherein said modifying includes adding, to the response data, a reference to the portion of the response data, wherein the modified response data instructs the first apparatus to store the portion of the response data and the reference to the portion of the response data in a storage that is locally accessible to the first apparatus;
the second apparatus sending the modified response data to the first apparatus;
the first apparatus storing the portion of the response data and the reference to the portion of the response data in the storage that is locally accessible to the first apparatus; and
the first apparatus sending the response data to the first computer.
9. The method of claim 8 , wherein the data request is part of a first communication from the first computer to the second computer, and wherein the first apparatus receives the data request by intercepting the first communication.
10. The method of claim 8 , wherein the data request is part of a first communication from the first computer to the first apparatus.
11. The method of claim 8 , wherein the response data is part of a second communication from the second computer to the first computer, and wherein the second apparatus receives the response data by intercepting the second communication.
12. The method of claim 8 , wherein the response data is part of a second communication from the second computer to the second apparatus.
13. The method of claim 8 , wherein the first computer communicates with the first apparatus over a first local area network, wherein the first apparatus communicates with the second apparatus over a wide area network, and wherein the second apparatus communicates with the second computer over a second local area network.
14. The method of claim 8 , wherein the storage that is locally accessible to the first apparatus is a database.
15. An apparatus, comprising:
a first receiving mechanism configured to receive a data request from a remote apparatus;
a first sending mechanism configured to send the data request to a computer;
a second receiving mechanism configured to receive response data from the computer, wherein the computer generates the response data based on the data request;
