Abstract

A system and method for sharing data from separate servers between browser frames. A first server opens a client browser frame set and loads data to a first frame. A second server is called from the first frame to open a window. Responsive to post command issued from the window, environment variables are passed from the second server to the first server and loaded data from the environment variables by the first server to a second frame of the frame set. Thereafter, data obtained from a second server, which is loaded in the second frame of the frame set, is available to the first frame.

Claims

1. A method for sharing data from separate servers between frames, comprising:

operating a first server to open a client browser frame set and load data to a first frame;

from said first frame, calling a second server to open a window;

issuing a post command from said window;

responsive to said post command, passing environment variables from said second server to said first server; and

loading data from said environment variables from said first server to a second frame of said frame set.

2. A method for sharing data between frames of a browser frameset, comprising the steps of:

loading from a first server into a browser a frameset including a plurality of frames;

loading first data from said first server into a first frame of said frame set;

responsive to user selection of a first selection device at said browser, issuing a first command to a second server;

said second server, responsive to said first command, opening a window in said browser;

responsive to user selection of a second selection device at said browser, issuing a second command to said second server;

said second server, responsive to said second command, communicating environment variables to said first server; and

responsive to said environment variables, said first server loading second data into said second frame.

3. The method of claim 2, said first selection device being a button within said first frame.

4. The method of claim 2, said second selection device being a button within said window.

5. The method of claim 2, said second server further responsive to said second command for closing said window.

6. The method of claim 2, said second command being a post command.

7. The method of claim 2, said environment variables including name/value pairs.

8. The method of claim 2, further comprising the step of:

said second server executing a program at said first server which receives said environment variables.

9. The method of claim 2, further comprising the step of:

communicating said second data from said second frame to said first frame.

10. The method of claim 2, said frame set including a navigation frame, a content frame, footer frame, a temporary data frame, and an application frame.

11. System for sharing data between frames of a browser frameset, comprising:

a first server for opening a frame set on said browser and loading data into a first frame of said frame set;

a second server responsive to a command from said browser for opening a window on said browser and responsive to a post command from said window for executing a program in said first server to pass environment variables to said first server;

said first server further responsive to said environment variables for loading second data into said second frame.

12. The system of claim 11, further comprising a selection device within said first frame for issuing said command.

13. The system of claim 11, said program being a Notes agent.

14. The system of claim 11, said browser transferring data from said second frame to said first frame.

15. The system of claim 11, said frame set comprising a navigation frame, a header frame, a content frame, a footer frame, a temporary data frame, and an application frame.

16. The system of claim 11, said first frame being any of said navigation frame, footer frame, or content frame and said second frame being said temporary data frame.

17. A program storage device readable by a machine, tangibly embodying a program of instructions executable by a machine to perform method steps for sharing data from separate servers between frames, said method steps comprising:

operating a first server to establish a frame set and load data to a first frame;

from said first frame, calling a second server to open a window;

issuing a post command from said window;

responsive to said post command, passing environment variables from said second server to said first server;

and

loading data from said environment variables from said first server to a second frame of said frame set.

18. A computer program product or computer program element for sharing data from separate servers between frames according to steps comprising:

operating a first server to establish a frame set and load data to a first frame;

from said first frame, calling a second server to open a window;

issuing a post command from said window;

responsive to said post command, passing environment variables from said second server to said first server;

and

loading data from said environment variables from said first server to a second frame of said frame set.
