Abstract

Systems and methods for collaborating over the Internet (or an intranet) in which two or more parties, such as a user and an agent, can share dynamic content generated by a web site server. Collaboration can be accomplished on live, dynamic pages without imposing a proxy server between user browsers and the web servers. Mechanisms prevent multiple submissions, and filters can be provided to selectively filter versions of a page for different users.

Claims

1. A method for providing collaboration between a first user and a second user comprising:

receiving, at a web site, a request from the first user with a browser;

processing the request with information related to the first user to create a page with dynamic content;

copying the page with dynamic content into a copy server without changing any locators in the page, the copy server having the page with dynamic content as a copied page;

providing, to the first user, a locator for the copied page of the copy server, the locator allowing the first user to access the copied page from the copy server; and

providing, to the second user, the locator for the copied page of the copy server, the locator allowing the second user to access the copied page from the copy server, the first user and the second user viewing versions of the same copied page; and

synchronizing access to the copied page to block multiple users from operating on the copied page, synchronizing including employing the locator by the first user for modifying the copied page such that the second user is blocked from modifying the copied page until the modifications performed by the first user are written to the copied page at the copy server from the modified dynamic content page.

2. The method of claim 1 further comprising:

identifying a collaboration set of users having the ability to access the copied page, the first and second users included in the collaboration set; and

permitting only one of the first and second users from operating on the copied page.

3. The method of claim 2 further comprising establishing a collaboration session by sending cookies between the copy server and the first and second user browsers, the copy server responsive to a collaboration server for sending cookies and identifying modifications to the collaboration set.

4. The method of claim 1 further comprising copying the copied page to each of the first and second users, the copied page residing on a respective user browser, wherein each of the first and second users access the copied page on the respected user browser, and wherein the copy server allows one of the first and second users to be operating on the copied page at the copy server.

5. The method of claim 4 wherein the second user corresponds to an agent browser responsive to the first user browser.

6. The method of claim 1 further comprising:

providing an informational message to the second user when the first user is operating on the copied page at the copy server; and

unblocking the second user when the first user completes operating on the copied page at the copy server.

7. The method of claim 1 further comprising:

determine which information of the copy page each of the first and second user is permitted to observer; and

filtering the content of the page displayed on the respective user browser of the first and second user.

8. The method of claim 7 further comprising discriminating between the filtered versions of the copied pages by identifying the corresponding request for the copied page emanating from each of the first and second user.

9. The method of claim 7 further comprising:

identifying the information to be limited in the copied page;

suppressing the identified information from the information sent to the browser of the second user by selectively sending according to the filter; and

;

receiving a form including information corresponding to the suppressed information from the first user.

10. The method of claim 1 wherein operating on the copied page further comprises identifying which of the first and second user is modifying the copied page.

11. A data communications device for providing collaboration between a first user and a second user comprising:

a web server operable to receive a request from the first user with a browser;

a page processor operable to process the request with information related to the first user to create a page with dynamic content;

a copy server operable to copy the page with dynamic content into a memory without changing any locators in the page, the copy server having the page with dynamic content as a copied page, the the web server operable to provide, to the first user, a locator for the copied page of the copy server, the locator allowing the first user to access the copied page from the copy server; and

to provide, to the second user, the locator for the copied page of the copy server, the locator allowing the second user to access the copied page from the copy server, the first user and the second user viewing versions of the same copied page; and

an adapter in the web server operable to synchronize access to the copied page to block multiple users from operating on the copied page, synchronizing access including employing the locator by the first user for modifying the copied page such that the second user is blocked from modifying the copied page until the modifications performed by the first user are written to the copied sage at the copy server from the modified dynamic content page.

12. The data communications device of claim 11 further comprising

a collaboration server operable to identify a collaboration set of users having the ability to access the copied page, the first and second users included in the collaboration set, and

a blocking mechanism, responsive to the copy server, operable to permit only one of the first and second users from operating on the copied page.

13. The data communications device of claim 12 wherein the collaboration server is further operable to establish a collaboration session by sending cookies between the copy server and the first and second user browsers, the copy server responsive to a collaboration server for sending cookies and identifying modifications to the collaboration set.

14. The data communications device of claim 11 wherein the web server is further operable to copying the copied page to each of the first and second users, the copied page residing on a respective user browser, wherein each of the first and second users access the copied page on the respected user browser, and wherein the copy server allows one of the first and second users to be operating on the copied page at the copy server.

15. The data communications device of claim 14 wherein the second user corresponds to an agent browser responsive to the first user browser.

16. The data communications device of claim 11 wherein the copy server is further operable to:

provide an informational message to the second user when the first user is operating on the copied page at the copy server; and

unblock the second user when the first user completes operating on the copied page at the copy server.

17. The data communications device of claim 11 further comprising a filter operable to determine which information of the copy page each of the first and second user is permitted to observer, the filter further operable to filter the content of the page displayed on the respective user browser of the first and second user.

18. The data communications device of claim 17 wherein the filter further comprises filtering code operable to discriminate between the filtered versions of the copied pages by identifying the corresponding request for the copied page emanating from each of the first and second user.

19. The data communications device of claim 18 wherein the filter is further operable to:

identify the information to be limited in the copied page;

suppress the identified information from the information sent to the browser of the second user by selectively sending according to the filter; and

receive a form including information corresponding to the suppressed information from the first user.

20. The data communications device of claim 11 wherein the copy server is further operable identify which of the first and second user is modifying the copied page.
