Abstract

A computer server includes processor and memory hardware. The processor hardware executes instructions including parsing a hypertext transfer protocol (HTTP) request from a first user agent to identify a first data object matching a set of characteristics and generating a new data element based on the HTTP request. The instructions include, in response to the first data object being present: extracting a first set of serialized data elements and serializing them with the new data element to generate a second data object. The instructions include, in response to the first data object being absent and a user associated with the first user agent being identifiable: determining a second set of serialized data elements based on an identity of the user, and serializing them with the new data element to generate the second data object. The instructions include transmitting an HTTP response including the second data object.

First claim

What is claimed is:

1. A computer-implemented method comprising:
parsing a received hypertext transfer protocol (HTTP) request from a user agent to identify a first impression cookie matching a set of characteristics;
generating a new impression based on the HTTP request;
updating an impression data structure based on the new impression;
in response to the first impression cookie being present,
extracting a first set of serialized impressions from the first impression cookie, and
generating a second impression cookie based on serializing the new impression and the first set of serialized impressions;

in response to the first impression cookie being absent and a user of the user agent being identifiable,
determining a second set of serialized impressions based on an identity of the user, and
generating the second impression cookie based on serializing the new impression and the second set of serialized impressions; and

transmitting a HTTP response to the user agent, wherein the HTTP response includes the second impression cookie.

2. The computer-implemented method of claim 1 wherein:
each impression in the second impression cookie is associated with a timestamp; and
the method further comprises determining an order of the impressions within the second impression cookie by sorting on the timestamps.

3. The computer-implemented method of claim 1 further comprising, in response to the first impression cookie being absent and a user of the user agent not being identifiable, generating the second impression cookie based on the new impression.

4. The computer-implemented method of claim 1 wherein generating the new impression includes generating the new impression based on information encoded in a uniform resource locator (URL) specified by the HTTP request.

5. The computer-implemented method of claim 1 further comprising identifying the user based on at least one of an internet protocol (IP) of the user agent and a cookie within the HTTP request that is distinct from the first impression cookie.

6. The computer-implemented method of claim 1 wherein determining the second set of serialized impressions includes at least one of sending a request indicating the identity of the user to a database server and consulting a cache according to the identity of the user.

7. The computer-implemented method of claim 1 wherein the HTTP response includes an image.

8. A computer-implemented method comprising:
parsing a received hypertext transfer protocol (HTTP) request from a user agent to identify whether an impression cookie is present;
generating a new impression based on the HTTP request;
updating an impression data structure based on the new impression;
in response to the impression cookie being present,
extracting a set of serialized impressions from the impression cookie, and
generating a new impression cookie based on serializing the new impression and the set of serialized impressions; and

transmitting a HTTP response to the user agent, wherein the HTTP response includes the new impression cookie.

9. The computer-implemented method of claim 8 wherein:
each impression in the new impression cookie is associated with a timestamp; and
the method further comprises determining an order of the impressions within the new impression cookie by sorting on the timestamps.

10. The computer-implemented method of claim 8 wherein generating the new impression includes generating the new impression based on information encoded in a uniform resource locator (URL) specified by the HTTP request.

11. The computer-implemented method of claim 8 further comprising transmitting the new impression and metadata to a database server, the metadata including information based on a user-agent string from the HTTP request.

12. The computer-implemented method of claim 8 wherein the HTTP response includes an image.

13. The computer-implemented method of claim 12 wherein the image is one pixel in height and one pixel in width.

14. A computer-implemented method comprising:
parsing a received hypertext transfer protocol (HTTP) request from a user agent to identify whether an impression cookie is present;
generating a new impression based on the HTTP request;
updating an impression data structure based on the new impression;
in response to the impression cookie being absent and a user of the user agent being identifiable,
determining a set of serialized impressions based on an identity of the user, and
generating a new impression cookie based on serializing the new impression and the set of serialized impressions; and

transmitting a HTTP response to the user agent, wherein the HTTP response includes the new impression cookie.

15. The computer-implemented method of claim 14 wherein:
each impression in the new impression cookie is associated with a timestamp; and
the method further comprises determining an order of the impressions within the new impression cookie by sorting on the timestamps.

16. The computer-implemented method of claim 14 further comprising, in response to the impression cookie being absent and a user of the user agent not being identifiable, generating the new impression cookie based on the new impression.

17. The computer-implemented method of claim 14 further comprising transmitting the new impression and metadata to a database server, the metadata including information based on a user-agent string from the HTTP request.

18. The computer-implemented method of claim 14 further comprising identifying the user based on at least one of an internet protocol (IP) of the user agent and a cookie within the HTTP request that is distinct from the impression cookie.

19. The computer-implemented method of claim 14 wherein determining the set of serialized impressions includes at least one of sending a request indicating the identity of the user to a database server and consulting a cache according to the identity of the user.

20. The computer-implemented method of claim 14 wherein the HTTP response includes an image.
