Abstract

Described herein are, among other things, systems and methods for synchronizing cookies across different domains, and leveraging such systems and methods for content delivery. For example, two parties hosting content under different domain names from one another may desire to synchronize identification or ‘ID’ cookies that hold identifiers for a given client and/or end-user, so that one or both of the parties can map a given identifier from one domain to the identifier used in the other domain. Without limitation, some techniques described herein leverage one or more proxy servers that may be part of a distributed computing platform known as a content delivery network. Further, by way of example, some of the techniques for cookie synchronization can be leveraged to accelerate the delivery of content on a website with content from multiple domains.

Claims

1. A system, comprising:

a first server associated with a first content provider and associated with a first domain name, the first server hosting a markup language file;

a second server associated with a second content provider and associated with a second domain name, the second server hosting an object referenced by a universal resource locator (URL) in the markup language file, the URL having a hostname component that contains the second domain name;

at least one proxy server that comprises circuitry forming one or more processors and memory holding computer-readable instructions that when executed by the one or more processors will cause the proxy server to;

receive from a client a request for the markup language file, and at least one cookie valid for the first domain;

request and receive the markup language file from the first server;

parse the markup language file to find the URL referencing the object;

determine that there is no stored association between the at least one first domain cookie and at least one cookie valid for the second domain;

upon the determination that the stored association does not exist, (a) modify the URL by replacing the second domain name in the URL'"'"'s hostname component with a third domain name that is aliased to a fourth domain name associated with the at least one proxy server, and (b) send the markup language file with the modified URL to the client.

2. The system of claim 1, wherein the third domain name is a subdomain of the second domain name.

3. The system of claim 1, wherein the scope of the at least one cookie valid for the second domain includes the second domain and the third domain name.

4. The system of claim 1, wherein the instructions when executed by the one or more processors will cause the at least one proxy server to:

receive a subsequent request for the markup language file from the client or another client, and determine that there is a stored association between the at least one first domain cookie and the at least one cookie valid for the second domain, and upon said determination, use the stored association to identify the at least one second domain cookie.

5. The system of claim 4, wherein the instructions when executed by the one or more processors will cause the at least one proxy server to:

upon the determination that the stored association exists, request the object from the second server using the at least one second domain cookie, in anticipation of receiving a request from the client or said another client for the object.

6. The system of claim 4, wherein the instructions when executed by the one or more processors will cause the at least one proxy server to:

upon the determination that the stored association exists, (i) modify the URL by replacing the second domain name in the URL'"'"'s hostname component with the first domain name, and (ii) send the markup language file with the modified URL from (i) to the client or said another client, in response to the subsequent request.

7. The system of claim 1, wherein the at least one first domain cookie and the at least one second domain cookie each include an identifier for the client or for an end-user.

8. The system of claim 1, wherein the instructions when executed by the one or more processors will cause the at least one proxy server to:

receive a request from the client for the object using the modified URL,

receive from the client at least one cookie valid for the second domain name, and

associate the at least one first domain cookie with the at least one second domain cookie.

9. A method performed by at least one computer, the method comprising:

receiving at least one cookie valid for a first domain name in a request from a client for content;

receiving a markup language file from a server associated with the first domain name;

examining the markup language file to find an embedded reference to an object, the reference pointing to a second domain name;

determining that there is no stored association between the at least one first domain cookie and at least one cookie valid for the second domain name;

upon the determination that the stored association does not exist, (a) modifying the reference to point to a third domain name that is aliased to a fourth domain name associated with the at least one computer, and (b) sending the markup language file with the modified reference to the client.

10. The method of claim 9, wherein the third domain name is a subdomain of the second domain name.

11. The method of claim 9, wherein the scope of the at least one cookie valid for the second domain includes the second domain and the third domain name.

12. The method of claim 9, further comprising:

receiving a subsequent request for the markup language file from the client or another client, and determine that there is a stored association between the at least one first domain cookie and the at least one cookie valid for the second domain, and upon said determination, use the stored association to identify the at least one second domain cookie.

13. The method of claim 12, further comprising:

upon the determination that the stored association exists, requesting the object from a second server using the at least one second domain cookie, in anticipation of receiving a request from the client or said another client for the object.

14. The method of claim 12, further comprising:

upon the determination that the stored association exists, (i) modifying the reference to point to the first domain name, and (ii) sending the markup language file with the modified reference from (i) to the client or said another client, in response to the subsequent request.

15. The method of claim 9 wherein the stored association is an association between an identifier in the at least one first domain cookie and an identifier in the at least one second domain cookie.

16. The method of claim 9, further comprising:

receiving a request from a client for the object using the modified reference;

receiving from the client at least one cookie valid for the second domain name;

associating the at least one first domain cookie with the at least one second domain cookie.

17. The method of claim 9, wherein the reference is a URL.
