Process for associating data requests with site visits

1. A method of classifying data requests from a user computing device, the method comprising:

accessing a record of data requests sent over a network by the user computing device to one or more hosts;

classifying at least a first data request represented in said record as being part of a visit to a first site; and

determining whether a subsequent data request represented in said record is part of the visit to the first site based at least partly on whether the subsequent data request is directed to a host that is classified as a source of forced content;

said method performed by a computer system.

2. The method of claim 1 , wherein the method comprises classifying the subsequent data request as being part of the visit to the first site in response to determining that the subsequent data request is directed to a host that is classified as a source of forced content.

3. The method of claim 2 , wherein the host is not a member of the first site.

4. The method of claim 1 , wherein the determination of whether the subsequent data request is part of the visit to the first site is additionally based on whether the host is one of a plurality of hosts that are classified as members of the first site.

5. The method of claim 1 , wherein the determination of whether the subsequent data request is part of the visit to the first site is additionally based on whether the subsequent data request is a request for an image.

6. The method of claim 1 , wherein the determination of whether the subsequent data request is part of the visit to the first site is additionally based on an amount of time that has transpired since a most recent interaction between the user computing device and the first site.

7. The method of claim 1 , wherein the method comprises classifying the subsequent data request as the start of a visit to a second site at least partly in response to determining that the subsequent data request (1) is not directed to a host classified as a source of forced content, (2) is not a request for an image, and (3) is not directed to a host that is a member of the first site.

8. A system capable of classifying data requests, the system comprising:

a computer data repository that stores a record of data requests associated with a user; and

a processor configured to classify the data requests by a process that comprises:

classifying at least a first data request represented in said record as being part of a visit by the user to a first site; and

determining whether a subsequent data request represented in said record is part of the visit to the first site based at least partly on whether the subsequent data request is directed to a host that is classified as a source of forced content.

9. The system of claim 8 , wherein the process comprises classifying the subsequent data request as being part of the visit to the first site in response to determining that the subsequent data request is directed to a host that is classified as a source of forced content.

10. The system of claim 8 , wherein the determination of whether the subsequent data request is part of the visit to the first site is additionally based on whether the host is classified as a member of the first site.

11. The system of claim 8 , wherein the determination of whether the subsequent data request is part of the visit to the first site is additionally based on whether the subsequent data request is a request for an image.

12. The system of claim 8 , wherein the determination of whether the subsequent data request is part of the visit to the first site is additionally based on an amount of time since a most recent interaction by the user with the first site.

13. The system of claim 8 , wherein the process comprises classifying the subsequent data request as the start of a visit to a second site at least partly in response to determining that the subsequent data request (1) is not directed to a host that is classified as a source of forced content, (2) is not a request for an image, and (3) is not directed to a host that is a member of the first site.

14. A computer system configured to access a record of data requests associated with a user, and to associate particular data requests represented therein with particular site visits by the user based on at least the following: (1) whether the data requests are directed to hosts that are classified as sources of forced content, and (2) whether the data requests are directed to hosts that are site members associated with open site visits.

15. The computer system of claim 14 , wherein the computer system is configured to associate the data requests with particular site visits based further on whether the data requests are requests for images.

16. The computer system of claim 14 , wherein the computer system is configured to associate the data requests with particular site visits based further on amounts of time that have transpired since most recent interactions by the user with particular sites.

17. The computer system of claim 14 , wherein the computer system is configured to associate the data requests with particular site visits based further on whether the requests are Secure Socket Layer requests.

18. The computer system of claim 14 , wherein the computer system is configured to treat a data request as a start of a new site visit at least partly in response to determining that the data request (1) is not directed to a host that is a member of an open site visit, (2) is not directed to a host that is classified as a source of forced content, and (3) is not a request for an image.
