Abstract

The present invention relates to an electronic system and its corresponding method of determining the attributes of a Web page without downloading the Web page. The electronic system includes a first electronic system and a second electronic system. In the second electronic system, a keyword describing the contents of the Web page is added to a file. The first electronic system transmits a request to the second electronic system for the file. The second electronic system transmits the file to the first electronic system, where, based on the keyword, it is determined whether to download the Web page.

Claims

1. A method of providing web page content information, comprising:

pre-fetching attributes of a web page without downloading the web page by transmitting a request from a first electronic system to a second electronic system for downloading a header of a web page, said header including an attribute field indicative of the content of the web page;

transmitting said header from said second electronic system to said first electronic system; and

displaying said attribute field on said first electronic system.

2. The method of claim 1 wherein said header is a HTTP header of the web page.

3. The method of claim 2 wherein transmitting said request comprises transmitting a HEAD command request from said first electronic system to said second electronic system.

4. The method of claim 1 wherein said attribute field comprises one or more words.

5. The method of claim 1 further comprising

determining whether to retrieve the web page from the second electronic system responsive to said attribute field.

6. The method of claim 4 further comprising:

providing a user keyword at said first electronic system;

comparing said user keyword with said one or more words of said attribute field; and

displaying an address of the web page when said comparing said user keyword with said one or more words provides a successful comparison.

7. A method comprising:

transmitting a user keyword from a first electronic system to a second electronic system;

transmitting a request from said second electronic system to a third electronic system to retrieve a header of a web page without retrieving the web page itself, the header including an attribute field indicative of the contents of the web page;

transmitting said header of the web page from said third electronic system to said second electronic system;

comparing said user keyword with said attribute field; and

transmitting an address of the web page from said second electronic system to said first electronic system when said comparing said user keyword with said attribute field provides a successful comparison.

8. The method of claim 7 further comprising transmitting said attribute field from said second electronic system to said first electronic system when said comparing said user keyword with said attribute field provides a successful comparison.

9. The method of claim 7 wherein said header is a HTTP header of the web page.

10. The method of claim 9 wherein transmitting said request comprises transmitting a HEAD command request from said second electronic system to said third electronic system.

11. The method of claim 7 further comprising displaying the address of the web page and one or more words of said attribute field on an output device on the first electronic system.

26. The method of claim 11 wherein said header is a HTTP header of the web page.

27. The method of claim 26 wherein said request comprises a HEAD command request.

12. An article of manufacture, comprising:

a computer usable medium having computer readable program code contained therein for causing a processor to determine at least one word that is indicative of a content of a web page;

computer readable program code for causing the processor to add said at least one word to a header of the web page; and

computer readable program code for causing the processor to transmit said header upon a request for said header without transmitting the web page.

13. The method of claim 12 wherein said header comprises a HTTP header of the web page.

14. The method of claim 13 wherein transmitting said HTTP header comprises transmitting said HTTP header upon receiving a HEAD command request.

15. An electronic system comprising:

a communication link;

a first electronic system coupled to said communication link, said first electronic system includes a memory element containing a header of a web page, said header includes an attribute field having one or more words indicative of a content of the web page, said first electronic system transmits said header without transmitting the web page in response to a request; and

a second electronic system coupled to said communication link, said second electronic system transmits said request to said first electronic system to retrieve said header of the web page to display the one or more words on an output device.

16. The electronic system of claim 15 wherein said header comprises a HTTP header of the web page.

17. The electronic system of claim 16 wherein said request is a HEAD command request for said HTTP header of the web page.

18. A method of providing web page content information comprising:

transmitting a first request from a first electronic system to a second electronic system to download a first web page;

transmitting said first web page from said second electronic system to said first electronic system, said first web page having an embedded link of a second web page;

transmitting a second request from said first electronic system to a third electronic system to retrieve a header of said second web page without retrieving the second web page;

transmitting said header of said second web page from said third electronic system to said first electronic system, said header including an attribute field indicative of a content of said second web page; and

displaying said attribute field.

19. The method of claim 18 wherein displaying said attribute field comprises displaying one or more words of said attribute field on an output device if said embedded link is selected.

20. The method of claim 18 wherein said header comprises a HTTP header of said second web page.

21. The method of claim 18 wherein said first request is a GET command request.

22. The method of claim 18 wherein said second request is a HEAD command request.

23. The method of claim 18 further comprising displaying said first web page.

24. The method of claim 18 wherein displaying said attribute field comprises displaying one or more words of said attribute field if a pointing device is placed substantially over the embedded link.

25. An article of manufacture, comprising:

a computer usable medium having computer readable program code contained therein for causing a processor to transmit a request to retrieve a header of a web page without retrieving the web page;

computer readable program code for causing the processor to receive said header of the web page, which includes an attribute field having one or more words indicative of a content of the web page;

computer readable program code for causing the processor to compare a user keyword with said one or more words; and

computer readable program code for causing the processor to display an address of the web page if said user keyword and the one or more words provide a successful comparison.

28. An apparatus, comprising:

a memory device including one or more instructions; and

a processor coupled to said memory device, said processor in response to said one or more instructions to,

transmit a first request to retrieve a first web page,

receive said first web page, said first web page having an embedded link of a second web page,

display said first web page,

transmit a second request to retrieve a header of said second web page without retrieving said second web page,

receive said header of said second web page, said header including an attribute field having one or more words indicative of a content of said second web page, and

display said one or more words.

29. The method of claim 28 wherein said header is a HTTP header of the second web page.

30. The method of claim 29 wherein said first request comprises a GET command request and second request comprises a HEAD command request.
