Abstract

The present invention sets forth a method for content responding, a method for content requesting, a content responder and a content requester. A content responder receives a first request from a content requester via a network. Then, the content responder generates a first content based on the first request. Then the content responder receives a second request from the content requester via the network. Then, the content responder generates a second content based on the second request. Next, the content responder compares the second content with the first content. After that, the content responder transmits a second response with regard to the second request to the content requester via the network. The second response is generated based on the result of comparison. According to the invention, if there is a very small difference between the first content and the second content, network bandwidth can be saved, the transmitting time of content will be reduced, and thus the waiting time of the user to view content will be reduced. The present invention is particular beneficial to the existing industries (for example, the banking industry) that adopt narrow band network widely.

Claims

1. A method for content responding, comprising:

receiving a first request via a network from a content requestor;

generating a first content based on the first request;

transmitting the first content as a first response via the network to the content requestor;

storing the first content;

receiving a second request via the network from the content requestor;

generating a second content based on the second request;

comparing the second content with the first content to generate a difference between the first content and the second content;

generating a second response based on the difference between the first content and the second content; and

transmitting the second response via the network to the content requestor;

wherein generating a second response based on the difference between the first content and the second content further comprises;

generating the second response to include the second content based upon a determination that the difference between the first content and the second content is greater than a predetermined threshold; and

generating the second response to include the difference between the first content and the second content based upon a determination that the difference between the first content and the second content is less than a predetermined threshold.

2. The method according to claim 1, wherein generating a second response based on the difference between the first content and the second content further comprises:

generating a flag indicating whether the second response includes the second content or the difference between the first content and the second content.

3. The method according to claim 1, wherein the difference between the first content and the second content is:

the second content adding a new content on the basis of the first content;

the second content replacing a part of content on the basis of the first content;

or

the second content removing a part of content on the basis of the first content.

4. The method of claim 1, further comprising:

employing a session mechanism to ensure that the first request and the second request are received from the same content requestor.

5. A method for content requesting, comprising the steps of:

transmitting, via a network to a content responder, a first request for a first content;

receiving, via the network from the content responder, a first response with regard to the first request, said first response comprising the first content;

acquiring the first content from the first response;

buffering the first content;

transmitting, via the network to the content responder, a second request for a second content;

receiving, via the network from the content responder, a second response with regard to the second request, said second response based on a difference between the first content and the second content; and

acquiring the second content from the second response;

wherein acquiring the second content from the second response further comprises;

acquiring the second content directly from the second response upon a determination that the second response includes the second content; and

acquiring the second content by combining the difference between the first content and the second content with the first content upon a determination that the second response includes the difference between the first content and the second content.

6. The method according to claim 5, wherein the second response further comprises:

a flag indicating whether the second response includes the second content or the difference between the first content and the second content.

7. The method according to claim 5, wherein the difference between the first content and the second content is:

the second content adding a new content on the basis of the first content;

the second content replacing a part of content on the basis of the first content;

or

the second content removing a part of content on the basis of the first content.

8. The method according to claim 5, further comprising:

employing at a client a session mechanism to ensure that the first request and the second request come from the same client.

9. A computer program product for content responding comprising a computer readable storage device having computer usable program code embodied therewith, said computer usable program code comprising:

computer usable program code configured to receive a first request via a network from a content requestor;

computer usable program code configured to generate a first content based on the first request;

computer usable program code configured to transmit the first content as a first response via the network to the content requestor;

computer usable program code configured to store the first content;

computer usable program code configured to receive a second request via the network from the content requestor;

computer usable program code configured to generate a second content based on the second request;

computer usable program code configured to compare the second content with the first content to generate a difference between the first content and the second content;

computer usable program code configured to generate a second response based on the difference between the first content and the second content; and

computer usable program code configured to transmit the second response via the network to the content requestor;

wherein the computer usable program code configured to generate a second response based on the difference between the first content and the second content further comprises;

computer usable program code configured to generate the second response to include the second content based upon a determination that the difference between the first content and the second content is greater than a predetermined threshold; and

computer usable program code configured to generate the second response to include the difference between the first content and the second content based upon a determination that the difference between the first content and the second content is less than a predetermined threshold.

10. The computer program product according to claim 9, wherein the computer usable program code configured to generate a second response based on the difference between the first content and the second content further comprises:

computer usable program code configured to generate a flag indicating whether the second response includes the second content or the difference between the first content and the second content.

11. The computer program product according to claim 9, wherein the difference between the first content and the second content is:

the second content adding a new content on the basis of the first content;

the second content replacing a part of content on the basis of the first content;

or

the second content removing a part of content on the basis of the first content.

12. The computer program product of claim 9, further comprising:

computer usable program code configured to employ a session mechanism to ensure that the first request and the second request are received from the same content requestor.
