Abstract

A method and system for preparing a web content file for downloading over a computer network. The method comprises the steps of receiving a request from a browser for a web content file; in response to receiving the request, reducing the size of the requested file by removing pre-identified subject matter from the file; and downloading to the browser the reduced size file. For example, the reducing step may include the step of removing comments and unused logic blocks from the file. These unused logic blocks are functions that are in the file but not used. The removing step may comprise the steps of consolidating duplicated logic blocks, and shortening recurring identifiers within the file. These duplicated functions may be consolidated by identifying the duplicated functions, and replacing the duplicated functions with a reference to a single function in a library.

Claims

1. A method of preparing a web content file for downloading over a computer network, comprising the steps:

receiving a request from a browser for a web content file;

in response to receiving the request, reducing the size of the requested file by removing pre-identified subject matter from the file; and

downloading to the browser the reduced size file.

2. A method according to claim 1, wherein the reducing step includes the step of removing comments and unused logic blocks from the file.

3. A method according to claim 2, wherein the unused logic blocks are functions that are in the file but not used.

4. A method according to claim 1, wherein the reducing step includes the step of consolidating duplicated logic blocks, and shortening recurring identifiers within the file.

5. A method according to claim 4, wherein the consolidating step includes the step of identifying duplicated functions and replacing the duplicated functions with a reference to a single function in a library.

6. A system for preparing a web content file for downloading over a computer network, comprising:

means for receiving a request from a browser for a web content file;

means for reducing the size of the requested file, in response to receiving the request, by removing pre-identified subject matter from the file; and

means for downloading to the browser the reduced size file.

7. A system according to claim 6, wherein the reducing means includes means for removing comments and unused logic blocks from the file.

8. A system according to claim 7, wherein the unused logic blocks are functions that are in the file but not used.

9. A system according to claim 6, wherein the reducing means includes the means for consolidating duplicated logic blocks, and means for shortening recurring identifiers within the file.

10. A system according to claim 9, wherein the consolidating means includes means for identifying duplicated functions and replacing the duplicated functions with a reference to a single function in a library.

11. A program storage device readable by machine and tangibly embodying a set of instructions for the machine to perform method steps for preparing a web content file for downloading over a computer network, said method steps comprising:

receiving a request from a browser for a web content file;

in response to receiving the request, reducing the size of the requested file by removing pre-identified subject matter from the file; and

downloading to the browser the reduced size file.

12. A program storage device according to claim 11, wherein the reducing step includes the step of removing comments and unused logic blocks from the file.

13. A program storage device according to claim 12, wherein the unused logic blocks are functions that are in the file but not used.

14. A program storage device according to claim 11, wherein the reducing step includes the step of consolidating duplicated logic blocks, and shortening recurring identifers within the file.

15. A program storage device according to claim 14, wherein the consolidating step includes the step of identifying duplicated functions and replacing the duplicated functions with a reference to a single function in a library.
