Abstract

In one implementation, a computer-implemented method includes receiving at a data server computer hosted at a first internet domain a request from a client computer for data to be used by an application SWF file received from a web server hosted at a second internet domain and executed by the client computer, the request includes the second internet domain and information specifying the requested data. The method further includes generating at least a portion of a data SWF file including the requested data and a domain identifier corresponding to the second internet domain, the domain identifier configured to specify that SWF formatted files associated with the second internet domain are permitted to access the requested data within the data SWF file. The method also includes transmitting the data SWF file from the data server computer to the client computer.

Claims

1. A computer-implemented method, the method comprising:

receiving at a data server computer hosted at a first internet domain a request from a client computer for data to be used by an application SWF file received from a web server hosted at a second internet domain and executed by the client computer, the request comprising the second internet domain and information specifying the requested data, wherein the application SWF file is a SWF formatted file;

generating, in response to the received request, at least a portion of a data SWF file comprising the requested data and a domain identifier corresponding to the second internet domain, wherein the data SWF file is a SWF formatted file, the domain identifier configured to specify that SWF formatted files associated with the second internet domain are permitted to access the requested data within the data SWF file; and

transmitting the data SWF file from the data server computer to the client computer, wherein the data SWF file is adapted to be accessed by the application SWF file to retrieve the requested data associated with the second internet domain.

2. The method of claim 1, further comprising compiling a template file into the data SWF file prior to receiving the request from a client computer for the data SWF file, wherein the template file is formatted in a scripting language that when compiled generates a SWF formatted file.

3. The method of claim 2, wherein compiling the template file into the data SWF file comprises compiling the template file to have a placeholder for the requested data and a placeholder for the domain identifier.

4. The method of claim 3, wherein generating at least a portion of the data SWF file comprises inserting into the data SWF file the requested data at the placeholder for the requested data and the domain identifier at the placeholder for the domain identifier.

5. The method of claim 3, further comprising fragmenting the data SWF file into five parts, wherein the five parts comprise a first part, a second part, a third part, a fourth part, and a fifth part, wherein the first part, the third part, and the fifth part correspond to non-placeholder parts of the data SWF file, and wherein the second part corresponds to the placeholder for the domain identifier and the fourth part corresponds to the placeholder for the requested data.

6. The method of claim 5, wherein generating at least a portion of the data SWF file comprises substituting the domain identifier for the second part and the requested data for the fourth part.

7. The method of claim 6, wherein generating at least a portion of the data SWF file further comprises adjusting a size of the second part to be a size of the domain identifier and adjusting a size of the fourth part to be a size of the requested data.

8. The method of claim 5, wherein transmitting the data SWF file comprises transmitting the five parts of the data SWF file one part at a time.

9. The method of claim 8, wherein transmitting the first part is performed concurrently with substituting the domain identifier for the second part.

10. The method of claim 1, wherein generating at least a portion of the data SWF file comprises compiling a template file with the requested data and the second internet domain into the data SWF file, wherein the template file is formatted in a scripting language that when compiled generates a SWF formatted file.

11. The method of claim 10, wherein transmitting the data SWF file comprises transmitting the data SWF file as a single part.

12. The method of claim 1, further comprising determining that the application SWF file is permitted to receive the requested data.

13. The method of claim 12, wherein determining that the application SWF file is permitted to receive the requested data comprises determining that the second internet domain is on a list of internet domains permitted to receive the requested data.

14. A system for transmitting a data vector graphic file to a client computer, the system comprising:

one or more servers, each comprising a processor and a memory, hosted at a first internet domain;

an interface to the one or more servers to receive a request from a client computer for data to be used by an application vector graphic file from a web server executed by the client computer, the web server hosted at a second internet domain, the request comprising the second internet domain and information specifying the requested data;

a means for generating, in response to the received request, at least a portion of a data vector graphic file comprising the requested data and a domain identifier corresponding to the second internet domain, the domain identifier specifying that application vector graphic files associated with the second internet domain are permitted to access the requested data contained within the data vector graphic file; and

a communication module to transmit the data vector graphic file from the one or more servers to the client computer, wherein the data vector graphic file is adapted to be accessed by the application vector graphic file to retrieve the requested data associated with the second internet domain.

15. The system of claim 14, further comprising:

a vector graphic compiler installed on the one or more servers to compile an vector graphic template into the data vector graphic file prior to receiving the request from a client computer for the data vector graphic file, wherein compiling the vector graphic template into the data vector graphic file comprises compiling the vector graphic template with a placeholder for the requested data and a placeholder for the domain identifier;

wherein generating at least a portion of the data vector graphic file comprises inserting into the data vector graphic file the requested data at the placeholder for the requested data and the domain identifier at the placeholder for the domain identifier.

16. The system of claim 15, further comprising:

a vector graphic file data size adjuster installed on the one or more servers to adjust a size of the data vector graphic file having the requested data inserted for the placeholder for the requested data and the domain identifier inserted for the placeholder for the domain identifier.

17. The system of claim 14, further comprising:

a response data generator installed on the one or more servers to generate the requested data in response to the request from the client computer.

18. A computer-implemented method, the method comprising:

compiling by a data server computer hosted at a first internet domain a template for a vector graphic file having a placeholder for an internet domain into a data vector graphic file;

executing by the data server computer the following operations when a request for the data vector graphic file is received from a client computer, wherein the request specifies at least a second internet domain of a third-party vector graphic file to access the data vector graphic file on the client computer;

substituting the second internet domain of the third-party vector graphic file for the placeholder for the internet domain in the data vector graphic file; and

sending to the client computer the data vector graphic file with the second internet domain of the third-party vector graphic file substituted, wherein the client computer authorizes access to the data vector graphic file by the third-party vector graphic file.

19. The method of claim 18, further comprising resizing the data vector graphic file to correspond to a size of the data vector graphic file with the second internet domain of the third-party vector graphic file substituted.

20. The method of claim 18, wherein the data vector graphic file is comprised of multiple parts and a first part of the multiple parts corresponds to the placeholder for the internet domain, wherein a second part of the multiple parts is sent to the client computer while the second internet domain of the third-party vector graphic file is being substituted into the first part.
