Abstract

A method that includes altering portions of a text of an original version of a digital document to produce a revised version of the digital document in which the text is shorter than the text of the original document, receiving over a communication channel a request for the digital document from a device connected to the channel, and transmitting the revised version over the communication channel in response to the request.

Claims

1. A method comprising:

altering portions of a text of an original version of a digital document to produce a revised version of the digital document in which the text is shorter than the text of the original document, the altering including segmenting the digital document into subdocuments, the altering being done based on a set of at least one preference, the set of at least one preference being associated with a device based on a unique identifier of the device and independent of an association with the digital document,

receiving over a communication channel a request for the digital document from the device, and

transmitting the subdocuments of the revised version over the communication channel in response to the request,

wherein at least one of the transmitted subdocuments includes a link to an adjacent subdocument.

2. The method of claim 1 in which altering portions of the text includes applying more than one transformation selectively to the text.

3. The method of claim 1 also including selecting transformations to be applied to the text as part of the altering step, based on preferences associated with the device.

4. The method of claim 3 in which the preferences are stored in advance of the request for a document.

5. The method of claim 3 in which the preferences are stored in a database associated with a server.

6. The method of claim 3 in which the preferences are indicated by the user through the interface of the device.

7. The method of claim 3 in which the preferences are indicated by the user through the interface of a device other than the device from which the request for the digital document is made.

8. The method of claim 3 in which the preferences are indicated on a form provided from a server.

9. The method of claim 3 in which preferences are stored for each device from which requests for documents may be received.

10. The method of claim 3 in which preferences are stored for each type of device from which requests for documents may be received.

11. The method of claim 3 in which the preferences are stored on the device.

12. The method of claim 3 in which the preferences are stored on the device using a cookie mechanism.

13. The method of claim 1 in which the altering depends on the type of the device.

14. The method of claim 13 also including receiving information from the device identifying the type of device.

15. The method of claim 1 in which the altering is performed at a proxy server.

23. The method of claim 1 in which the digital document comprises a web page.

24. The method of claim 1 also including transmitting fewer than all of the subdocuments in response to the request.

25. The method of claim 1 in which the digital document comprises an e-mail.

26. The method of claim 1 in which altering portions of a text comprises altering portions of a text based on preferences associated with a device and independent of an association with the digital document.

27. The method of claim 1 in which altering portions of a text comprises altering portions of a text based on preferences related to at least one capability of the device.

28. The method of claim 1 in which altering portions of a text comprises altering portions of a text based on preferences related to at least one capability of the device, and independent of a relation to an ability of a user of the device.

29. The method of claim 1, wherein the segmenting subdocuments comprises:

determining a maximum document size permissible by the device;

converting the digital document into a specific markup language document; and

dividing the specific markup language document into a number of segments of a predetermined length.

30. The method of claim 29, wherein the number of segments is determined by dividing a size of the digital document by the maximum document size permissible by the device.
