Abstract

In one embodiment, a method includes receiving a request from a client device, the request including one or more device dimensions associated with the client device. The method further includes identifying a set of one or more content profiles, where each identified content profile is associated with one or more content-profile dimensions that are compatible with the received device dimensions. The method also includes determining whether a previously created content manifest corresponds to the identified set of content profiles. The method also includes, in response to a determination that a previously created content manifest corresponds to the identified set of content profiles, sending to the client device a uniform resource identifier (URI) identifying a resource that includes the previously created content manifest.

Claims

1. A method comprising:

receiving a request from a client device, the request comprising one or more device dimensions associated with the client device;

identifying a set of one or more content profiles, wherein each identified content profile is associated with one or more content-profile dimensions that are compatible with the received device dimensions;

determining whether a previously created content manifest corresponds to the identified set of content profiles, wherein the content manifest corresponds to a plurality of content profiles that apply to a plurality of devices, the plurality of devices comprising a first set of devices and a second set of devices that have at least one second-set device dimension that is different than the dimensions of the first set of devices;

in response to a determination that a previously created content manifest corresponds to the identified set of content profiles, sending to the client device an initial uniform resource identifier (URI) identifying a resource that includes the previously created content manifest;

receiving a new content profile having a content-profile dimension that corresponds to the at least one second-set device dimension that is different than the dimensions of the first set of devices;

creating a second-set content manifest corresponding to the plurality of content profiles and the new content profile;

sending the second-set content manifest to a content delivery network (CDN) for distribution by the CDN;

transmitting a request to the CDN to create a copy of the previously created content manifest;

receiving from the CDN a new URI corresponding to the copy of the previously created content manifest;

transmitting a request to the CDN to delete the previously created content manifest;

receiving from the CDN a second-set URI identifying a resource of the CDN that includes the second-set content manifest;

sending the second-set URI to one or more devices in the second set of devices;

receiving a request from a client device in the first set of devices for a content manifest, the request sent in response to a determination by the client device in the first set of devices that the initial URI no longer corresponds to any content manifest; and

sending to the client device in the first set of devices the new URI.

2. The method of claim 1, further comprising, in response to a determination that a previously created content manifest corresponding to the identified set of content profiles does not exist:

creating a new content manifest, the new content manifest corresponding to the identified set of content profiles;

sending the new content manifest to the CDN for distribution by the CDN;

receiving from the CDN a first URI identifying a resource of the CDN that includes the new content manifest; and

sending the first URI to the requesting client device.

3. The method of claim 1, wherein the device dimensions associated with the client device comprise one or more of a device model, a display size, a display resolution, a capability, a language, a geographic location, a store or company associated with the client device, or a file type or codec supported by the client device.

4. The method of claim 1, wherein the content-profile dimensions associated with a content profile comprise one or more of a language supported by the content profile, a geographic location where the content profile applies, an identification of a device dimension supported by the content profile, a file type or codec associated with the content profile, how a content item of the content profile is to be used, a time or date restriction for the content profile, or a store or company associated with the content profile.

5. The method of claim 1, wherein the content-profile dimensions being compatible with the received device dimensions comprises each device dimension of the one or more received device dimensions matching a corresponding content-profile dimension of the one or more content-profile dimensions.

6. The method of claim 1, wherein each content profile comprises one or more content-item identifiers, wherein each content-item identifier is a unique identifier that identifies a particular content item associated with the content profile.

7. The method of claim 6, wherein each content item comprises a document, file, application, image, video, audio file, computer-readable file, or command configured to be stored, displayed, operated, or played by the client device.

8. The method of claim 1, wherein each content manifest comprises one or more content-item identifiers, wherein each content-item identifier is a unique identifier that identifies a particular content item associated with that content manifest.

9. The method of claim 1, wherein the URI that identifies the resource that includes the previously created content manifest corresponds to a web location of the CDN that includes the previously created content manifest.

10. The method of claim 1, wherein determining whether the previously created content manifest corresponds to the identified set of content profiles comprises:

generating a hash of content-profile identifiers associated with the set of content profiles;

comparing the generated hash to a content-manifest hash, wherein the content-manifest hash comprises a hash of content-profile identifiers associated with the content manifest; and

determining whether the generated hash matches the content-manifest hash.

11. The method of claim 1, further comprising:

receiving a new content item;

sending the new content item to the CDN, wherein the CDN is configured to provide the new content item to a plurality of client devices; and

receiving from the CDN a first URI identifying a resource of the CDN configured to provide the new content item to the plurality of client devices.

12. The method of claim 1, further comprising:

receiving a new content item; and

determining one or more content-item dimensions associated with the new content item, wherein the content-item dimensions are used to perform a client-side or server-side determination of whether the new content item applies to a particular client device.

13. The method of claim 12, further comprising, by the particular client device, performing a client-side determination of whether the new content item applies to the particular client device.

14. The method of claim 1, further comprising:

receiving a second content profile and one or more content-profile dimensions associated with the second content profile, wherein the second content profile comprises one or more content-item identifiers, wherein each content-item identifier is a unique identifier that identifies a particular content item associated with the second content profile; and

generating a content-profile identifier that identifies the second content profile.

15. The method of claim 1, wherein the request to the CDN to create a copy of the previously created content manifest and the request to the CDN to delete the previously created content manifest comprise sending the second-set content manifest to the CDN.

16. One or more non-transitory computer-readable storage media embodying instructions that are operable when executed to:

receive a request from a client device, the request comprising one or more device dimensions associated with the client device;

identify a set of one or more content profiles, wherein each identified content profile is associated with one or more content-profile dimensions that are compatible with the received device dimensions;
