Abstract

A method for controlling display of a web page on the client, the contents in said web page being assigned different priorities, includes sending an access request for the web page from the client to the server; in response to said access request, the server sending controllers for implementing prioritization of said contents in the web page to the client, and the controllers retrieving the web page contents the server according to the priority order thereof for display. With the system and method, it is possible to prioritize different contents in a web page and to ensure contents with higher priority are downloaded and displayed earlier than those with lower priority, and thereby avoiding the disadvantage of multi-thread parallel download in the prior art.

Claims

1. A method for controlling display of contents of a web page on a client, said method comprising the steps of:

sending an access request for the web page from the client to a server;

in response to said access request, receiving from said server controllers for implementing prioritization of said contents in the web page; and

said controllers retrieving said contents of the web page from the server according to priority order for display.

2. The method according to claim 1, wherein said controller retrieving said contents of the web page from the server according to priority order for display further comprises:

retrieving the contents to the client in accordance with a priority of each of said contents; and

displaying the contents on the client in accordance with the priority of each of said contents.

3. The method according to claim 2, wherein said retrieving the contents to the client in accordance with the priority of each of said contents further comprises:

invoking a demand helper and a view activator in accordance with the priority of each of said contents; and

retrieving said content by said demand helper by using a unique identifier of said content.

4. The method according to claim 3, wherein said retrieving said content by said demand helper by using the unique identifier of said content further comprises:

determining whether to retrieve a particular content based on a predetermined policy;

wherein said predetermined policy includes at least one of the following;

content priority, current server status, IP address of the client issuing the web page request, and

wherein said predetermined policy is dynamically changeable during runtime.

5. The method according to claim 4, wherein said determining whether to retrieve a particular content based on a predetermined policy further comprises:

monitoring current server status;

determining whether to retrieve a particular content based on content priority, monitored server status and the predetermined policy.

6. The method according to claim 3, wherein said retrieving said content by said demand helper by using a unique identifier of said content further comprises:

sending a demand for content retrieving to a front dispatcher,

finding a delegate corresponding to the content by the front dispatcher by using the unique identifier of said content, and

operating on the content by the delegate before retrieving the content back to the client.

7. The method according to claim 2, wherein said displaying the content on the client in accordance with the priority of each of said content further comprises:

transferring retrieved content to a view controller by a view activator;

displaying, by the view controller, the retrieved content on a client browser.

8. The method according to claim 1, further comprising:

in response to said request, receiving from the server native content as well as the controllers for implementing prioritization of contents in the web page to the client;

said client displaying said native content, and

said controllers retrieving elements from the server according to the priority order of the elements for display.

9. The method according to claim 8, wherein said native content comprises native content framework and native content body, and said native content body can be empty.

10. A server for controlling display of contents of a web page on a client comprising:

request receiving means for receiving an access request for a web page from the client; and

response sending means for, in response to said access request, sending controllers for implementing prioritization of said contents in the web page to the client.

11. The server according to claim 10, wherein said controller comprising demand controller and view controller, said demand controller is used for retrieving content to the client in accordance with a priority order of each of said contents, and said view controller is used for displaying the content on the client in accordance with the priority order of each of said contents.

12. The server according to claim 10, wherein said demand controller further comprising at least one demand helper corresponding to the content, said at least one demand helper being invoked according to the order of content priority, so as to retrieve each of said contents.

13. The server according to claim 10, further comprising:

a filter module, comprising;

a policy manager, containing a predetermined policy,

a filter manager, for determining whether to retrieve a particular content based on the predetermined policy,

wherein said predetermined policy includes at least one of the following;

content priority, current server status, IP address of the client issuing the web page request, and wherein said predetermined policy is dynamically changeable during runtime.

14. The server according to claim 13, said filter module further comprising:

metering manager, for monitoring the current server status; and

filter manager, for determining whether to retrieve a particular content based on content priority, monitored server status and predetermined policy.

15. The server according to claim 12, further comprising:

a front dispatcher, each having a particular function, for receiving the demand for content retrieving from the demand helper, and finding the delegate corresponding to the content, and

a delegate, for operating on the content so as to return the content back to the client.

16. The server according to claim 10, wherein said view controller further comprising view activators for receiving retrieved content from the server, so as for the view controller to display.

17. The server according to claim 10, wherein said response sending means sends native content and the controllers for implementing prioritization of the contents in the web page to the client.

18. The server according to claim 17, wherein said native content comprising native content framework and native content body, and said native content body can be empty.

19. A client for displaying contents of a web page comprising:

request sending means for sending an access request for the web page to a server;

response receiving means for receiving from the server controllers for implementing prioritization of said contents in the web page from the server, said controllers retrieving contents from the server according the priority order of the contents; and

a browser for displaying the retrieved contents.

20. A system for controlling display of a web page comprising:

a server, comprising;

request receiving means for receiving an access request for a web page from a client;

response sending means for, in response to said access request, sending controllers for implementing prioritization of said contents in the web page to the client; and

a client, comprising;

request sending means for sending an access request for the web page to the server;

response receiving means for receiving from the server controllers for implementing prioritization of said contents in the web page from the server, so that said controllers retrieving contents from the server according the priority order of the contents; and

a browser for displaying the retrieved contents.
