1. A method of determining browsing history of a web application, the method comprising:

collecting, by executing instructions via at least one second thread different from a first thread, a plurality of web requests associated with a web application, the at least one second thread executing a web browser analyzer that is prevented from accessing browser history, the web browser analyzer having access to Hypertext Transfer Protocol (HTTP) data associated with the plurality of requests, the first thread executing the web application, the first thread and the at least one second thread executing on at least one processor;

logging, by executing instructions via the at least one second thread of the web browser analyzer, the HTTP data associated with the plurality of web requests;

parsing, by executing instructions via at least one of a data packet analyzer or the web browser analyzer, the HTTP data;

for a web request in the plurality of web requests, determining, by executing instructions via the at least one second thread, a count indicating a number of other ones of the plurality of web requests that include a referrer identifying the web request based on the parsed HTTP data; and

in response to the count exceeding a threshold, providing, by executing instructions via the at least one second thread, a uniform resource locator (URL) of a parent web request via the web browser analyzer, the threshold calculated based on a root mean square of counts pertaining to the other ones of the plurality of web requests.

2. The method as defined in claim 1 , further including adding, by executing instructions via the at least one second thread of the at least one processor, a webpage identified in the web request to a browsing history list.

7. The method as defined in claim 6 , further including removing, by executing instructions via the at least one second thread of the at least one processor, web requests from the array based on an exceeded time duration of the web requests being in the array.

8. The method as defined in claim 6 , further including removing, by executing instructions via the at least one second thread of the at least one processor, web requests from the array based on later incoming web requests into the array having respective counts greater than the threshold.

9. The method as defined in claim 6 , further including removing, by executing instructions via the at least one second thread of the at least one processor, the least one web request from the array based on at least one of:

a time duration to which the least one web request has been placed into the array, or

a later received web request having a respective number of referrer counts exceeding a referrer count corresponding to the least one web request in the array.

10. The method as defined in claim 1 , further including storing, by executing instructions via the at least one second thread of the at least one processor, the web request.

11. The method as defined in claim 1 , further including discarding, by executing instructions via the at least one second thread of the at least one processor, a web request of the plurality of web requests that is not determined to be a parent web request.

12. The method as defined in claim 1 , wherein the method of claim 1 is repeated for another web request in the plurality of web requests.

13. The method as defined in claim 1 , further including discarding a web request of the plurality of collected web requests with a respective referrer count that does not meet the threshold.

14. The method as defined in claim 1 , wherein the method of claim 1 is repeated for a second plurality of collected web requests.

15. The method as defined in claim 1 , wherein the first thread is executed on a first processor of a first device and the second thread is executed on a second processor of a second device different from the first device.

16. A tangible machine readable medium comprising instructions, which when executed, cause at least one processor to at least:

determine, via at least one second thread different from a first thread, a number of referrers corresponding to respective web requests of a plurality of web requests associated with a web application, the first thread executing the web application, the first thread and the at least one second thread executing on the at least one processor, the at least one second thread executing a web browser analyzer that is prevented from accessing browser history, the web browser analyzer having access to Hypertext Transfer Protocol (HTTP) data associated with the plurality of requests;

log, via the at least one second thread of the web browser analyzer, the HTTP data associated with the plurality of web request;

parse, via at least one of a data packet analyzer or the web browser analyzer, the HTTP data;

identify, via the at least one second thread, a web request of the plurality of web requests that has a respective number of referrers that exceeds a threshold as a parent web request based on the parsed HTTP data, the threshold calculated for a web request of the plurality of web requests based on a root mean square of referrer counts corresponding to other web requests of the plurality of web requests; and

provide a uniform resource locator (URL) of the parent request.

17. The machine readable medium as defined in claim 16 , wherein the instructions further cause the at least one processor to filter, via the second thread, a web request that has a respective number of referrers meeting the threshold.

18. The machine readable medium as defined in claim 17 , wherein filtering the web request occurs based on detection of at least one of an in-page request, a script, a cascading style sheet (CSS) request, or a ping.

19. The machine readable medium as defined in claim 16 , wherein the instructions further cause the at least one processor to place, via the second thread, the web request having numbers of referrers that meet the threshold into an array, wherein the array is to be updated based on at least one of a time duration of web requests placed in the array, or later incoming web requests having a greater number of respective number of referrers than the web request.

20. The machine readable medium as defined in claim 16 , wherein the instructions further cause the at least one processor to store, via the second thread, the identified web request.

21. The machine readable medium as defined in claim 16 , wherein the instructions further cause the at least one processor to discard, via the second thread, a web request of the plurality of web requests that has a respective number of referrers that do not meet the threshold.

22. The machine readable medium as defined in claim 16 , wherein the instructions further cause the at least one processor to repeat the instructions of claim 16 based on a second plurality of web requests.

23. An apparatus comprising:

at least one memory;

instructions; and

at least one processor to execute the instructions to:

determine, via at least one second thread different from a first thread, a number of referrers corresponding to respective web requests of a plurality of web requests associated with a web application, the first thread executing the web application, the first thread and the at least one second thread executing on the at least one processor, the at least one second thread executing a web browser analyzer that is prevented from accessing browser history, the web browser analyzer having access to Hypertext Transfer Protocol (HTTP) data associated with the plurality of requests,

log, via the at least one second thread of the web browser analyzer, the HTTP data associated with the plurality of web request,

parse, via at least one of a data packet analyzer or the web browser analyzer, the HTTP data,

identify, via the at least one second thread, a web request of the plurality of web requests that has a respective number of referrers that exceeds a threshold as a parent web request based on the parsed HTTP data, the threshold calculated for a web request of the plurality of web requests based on a root mean square of referrer counts corresponding to other web requests of the plurality of web requests, and

provide a uniform resource locator (URL) of the parent request.

24. The apparatus as defined in claim 23 , wherein the at least one processor is to filter, via the second thread, a web request that has a respective number of referrers meeting the threshold.
