Abstract

An e-mail server is configured so that when an e-mail having an attachment is received at the server, a web-based URL is included in the e-mail to identify a fulfillment site at which a handler (e.g., a plug-in) for the attachment may be obtained. The e-mail is delivered to a client machine. When the user of the machine selects the attachment to open, the e-mail application checks to determine if there is a registered handler in the client machine to handle the attachment. If there is no installed attachment handler (or if the handler is not available), the e-mail application automatically contacts the fulfillment site by opening a browser (or other viewer) to the URL that was included with the e-mail. When the user enters the required data, the fulfillment site sends the attachment handler. Upon receipt, the plug-in self-installs and opens the attachment in a seamless manner.

Claims

1. A method of web-based delivery of a handler to handle an e-mail attachment, comprising:

at a client, responsive to a selection of an e-mail attachment, automatically opening a browser to a given URL if the client is not capable of opening the attachment;

serving a dialog to the client from the given URL;

upon entry of given subscription information in the dialog, applying a given use restriction to a handler; and

serving the handler to the client.

2. The method as described in claim 1 further including the step of:

at the client, automatically installing the handler.

3. The method as described in claim 2 further including the step of:

at the client, automatically uninstalling the handler upon a given occurrence.

4. The method as described in claim 3 wherein the given occurrence is invocation of the handler a given number of times as defined by the given use restriction.

5. The method as described in claim 3 wherein the given occurrence is a given passage of time as defined by the given use restriction.

6. The method as described in claim 1 wherein the given use restriction restricts a given function of the handler.

7. The method as described in claim 6 wherein the given function is an edit function.

8. The method as described in claim 6 wherein the given function is a print function.

9. The method as described in claim 1 wherein the step of applying a given use restriction applies an encrypted usage count to the handler.

10. The method as described in claim 1 wherein the given URL is associated with the e-mail attachment prior to delivery of the e-mail attachment to the client.

11. A method of web-based delivery of a handler to handle an e-mail attachment, comprising:

serving a fulfillment dialog in response to a client request initiated upon selection of an e-mail attachment that cannot be processed at a local client system;

upon entry of given billing and subscription information in the dialog, applying a given use restriction to a self-installing handler; and

serving the handler to the local client system.

12. The method as described in claim 11 wherein, upon receipt at the local client system, the handler self-installs itself and processes the e-mail attachment.

13. The method as described in claim 11 wherein the step of applying a given use restriction associates a usage count to the handler.

14. The method as described in claim 13 wherein the usage count is encrypted to prevent alteration.

15. The method as described in claim 11 wherein the step of applying a given use restriction associates a time period during which the handler may be used to process the e-mail attachment.

16. The method as described in claim 11 wherein the step of applying a given use restriction restricts a given function of the handler.

17. A computer program product in a computer useable medium operative at a server, comprising:

means for serving a fulfillment dialog in response to a client request initiated upon selection of an e-mail attachment that cannot be processed at a local client system;

means responsive to entry of given information in the dialog for encrypting a self-installing handler with a given access count; and

means for serving the self-installing handler to the local client system.

18. A server, comprising:

a handler;

means for serving a fulfillment dialog in response to a client request initiated upon selection of an e-mail attachment that cannot be processed at a local client system;

means responsive to entry of given information in the dialog for applying a given use restriction to the handler based on the information; and

means for serving the handler to the local client system.

19. The server as described in claim 18 wherein the means for applying a given use restriction comprises means for encrypting the handler with an access count.

20. The server as described in claim 18 wherein the means for applying a given use restriction comprises means for restricting a given function of the handler.

21. The server as described in claim 18 wherein the means for applying a given use restriction comprises means for controlling the handler to uninstall itself from the local client system after a given time period has elapsed.
