Abstract

Methods, systems and computer program products are provided for synchronizing views among a plurality of different Web browsers in a network environment by selecting a source root frame displayed by a source browser included in the plurality of different web browsers and generating a description of a frame hierarchy from the selected source root frame. The description of a frame hierarchy is transmitted over the network environment and the frame hierarchy duplicated from the description into a selected target root frame of at least one of the plurality of different Web browsers.

Claims

1. A method of synchronizing views among a plurality of different Web browsers in a network environment, comprising the steps of:

selecting a source root display frame displayed by a source browser included in said plurality of different web browsers;

generating a description of browser display frames associated with the source root display frame as a frame hierarchy of browser display frames from said selected source root frame;

transmitting said description of a frame hierarchy over the network environment; and

duplicating said frame hierarchy from said description into a selected target root display frame of at least one of said plurality of different Web browsers to thereby provide the browser display frames in the frame hierarchy to the at least one of said plurality of different Web browsers so as to synchronize the view of the source browser and the at least one of said plurality of different Web browsers.

2. The method of claim 1, wherein said step of generating a description comprises the steps of:

capturing an entry about said source root frame; and

capturing an entry about each subframe in said frame hierarchy.

3. The method of claim 2, wherein said entry about said source root frame comprises a URL contained in said source root frame and wherein said entry about each subframe comprises:

a name of each subframe;

a URL contained in said each subframe; and

a depth of said each subframe in said frame hierarchy.

4. The method of claim 1, wherein said step of duplicating said frame hierarchy using said description comprises the steps of:

determining whether a URL currently loaded in said target root frame is identical to a URL loaded into said source root frame; and

initiating a load of said URL of said source root frame into said target root frame if said determination is false.

5. The method of claim 4, further comprising the steps of:

retrieving from said description a plurality of entries, each of said plurality of entries providing information about an associated subframe in said frame hierarchy;

determining for each of said entries whether said associated subframe has a corresponding subframe of said target root frame;

determining whether said URL for said associated subframe is loaded into said corresponding subframe; and

initiating a load of said URL into said corresponding subframe if said URL is not loaded into said corresponding subframe.

6. The method of claim 1, wherein said step of generating a description is performed by a Collaboration Script executing within a Collaboration Frame in the browser display, and wherein said step of duplicating said frame hierarchy is performed by said Collaboration Script executing within a Collaboration Frame in the browser display.

7. The method of claim 6, wherein said Collaboration Frame is not visible to the user.

8. The method of claim 1, wherein said step of transmitting comprises the steps of:

transmitting said description from said source browser to a collaboration server; and

transferring said description from said collaboration server to at least one of said plurality of different web browsers.

9. The method of claim 1, wherein said step of generating a description is initiated by user action.

10. The method of claim 1, wherein said step of using said description is initiated by user action.

11. A system for synchronizing views among a plurality of different Web browsers in a network environment, comprising the steps of:

means for selecting a source root display frame displayed by a source browser included in said plurality of different web browsers;

means for generating a description of browser display frames associated with the source root display frame as a frame hierarchy of browser display frames from said selected source root frame;

means for transmitting said description of a frame hierarchy over the network environment; and

means for duplicating said frame hierarchy from said description into a selected target root display frame of at least one of said plurality of different Web browsers to thereby provide the browser display frames in the frame hierarchy to the at least one of said plurality of different Web browsers so as to synchronize the view of the source browser and the at least one of said plurality of different Web browsers.

12. The system of claim 11, wherein said means for generating a description comprises:

means for capturing an entry about said root source frame; and

means for capturing an entry about each subframe in said frame hierarchy.

13. The system of claim 12, wherein said entry about said source root frame comprises a URL contained in said source root frame and wherein said entry about each subframe comprises:

a name of each subframe;

a URL contained in said each subframe; and

a depth of each subframe in said frame hierarchy.

14. The system of claim 11, wherein said means for duplicating said frame hierarchy using said description comprises:

means for determining whether a URL currently loaded in said target root frame is identical to a URL loaded into said source root frame; and

means for initiating a load of said URL of said source root frame into said target root frame if said determination is false.

15. The system of claim 14, further comprising:

means for retrieving from said description a plurality of entries, each of said plurality of entries providing information about an associated subframe in said frame hierarchy;

means for determining for each of said entries whether said associated subframe has a corresponding subframe of said target root frame;

means for determining whether said URL for said associated subframe is loaded into said corresponding subframe;

means for initiating a load of said URL into said corresponding subframe if said URL is not loaded into said corresponding subframe.

16. The system of claim 11, wherein said means for generating a description is performed by a Collaboration Script executing within a Collaboration Frame in the browser display, and wherein said means for duplicating said frame hierarchy is performed by said Collaboration Script executing within a Collaboration Frame in the browser display.

17. The system of claim 16, wherein said Collaboration Frame is not visible to the user.

18. The system of claim 11, wherein said means for transmitting comprises:

means for transmitting said description from said source browser to a collaboration server;

means for transferring said description from said collaboration server to at least one of said plurality of different web browsers.

19. The system of claim 11, wherein said means for generating a description is initiated by user action.

20. The system of claim 11, wherein said means for using said description is initiated by user action.

21. A computer program product recorded on computer readable medium for synchronizing views among a plurality of different Web browsers in a network environment, comprising:

computer readable means for selecting a source root display frame displayed by a source browser included in said plurality of different web browsers;

computer readable means for generating a description of browser display frames associated with the source root display frame as a frame hierarchy of browser display frames from said selected source root frame;
