Abstract

Systems and methods for delivering cross-site auto-play media are described herein. The server can receive, from a client device, a request for media content at a first domain embedded in a content element from a second domain. The request can include an identifier indicating that the client device is configured to restrict cross-domain redirection. The server can determine, responsive to identifying the identifier indicating that the client device is configured to restrict cross-domain redirection, that the request comprises a content type header having a first predetermined value. The server can generate, responsive to the determination, a response comprising the media content element in a body of the response. The server can transmit the response to the client device. Receipt of the response can cause the client device to extract the media content element from the body of the response and to render the media content element.

3. The method of claim 1, wherein receiving the request for media content element further comprises receiving the request for media content element, the predefined identifier of the request including an application type identifier for an application executing on the client device;

and

wherein the method further comprises;

identifying, by the data processing system, that the application type identifier for the application executing on the client device corresponds to a predesignated application, and

determining that the request comprises the content type header having the first predetermined value, responsive to identifying that the application type identifier corresponds to the predesignated application.

4. The method of claim 1, further comprising searching, by the data processing system, a whitelist for the first domain, the whitelist specifying a plurality of domains permitted with the embedded media content element;

and

wherein generating the response further comprises generating the response responsive to determining that the first domain is on the whitelist.

5. The method of claim 1, further comprising:

receiving, by the data processing system from the client device, a second request for media content element at the first domain embedded in the content slot from the second domain, the second request received prior to the request, the second request including the predefined identifier indicating that the client device is configured to restrict cross-domain restriction;

determining, by the data processing system, responsive to identifying the first domain as different from the second domain and to identifying that the second request includes the predefined identifier, that the second request comprises a content type header having a second predetermined value different from the first predetermined value;

generating, by the data processing system, responsive to determining that the request comprises the content type header having the second predetermined value, a second response comprising a header and a body, the body of the second response comprising an address for the requested media content element without redirecting the client device, the header of the second response comprising a status identifier indicating success; and

transmitting, by the data processing system, the second response to the client device, receipt of the second response causing the client device to transmit the request for the requested media content element to the extracted address.

6. The method of claim 5, further comprising determining, by the data processing system, responsive to receiving the second request from the second client device, that a number of redirect requests for the second client device is less than a predefined threshold;

and

wherein determining that the second request comprises the content type header type having the second predetermined value further comprises determining that the second request comprises the content type header type having the second predetermined value, responsive to determining that the number of redirect requests is less than the predefined threshold.

7. The method of claim 5, wherein the second predetermined value of the content type header in the second response indicates textual content.

8. The method of claim 1, wherein the first predetermined value of the content type header in the response indicate non-textual content.

9. The method of claim 1, wherein generating the response further comprises generating the request including executable code in the body of the response to instantiate a media player.

10. The method of claim 1, wherein the response comprises a status code lacking a redirect code.

11. A system for delivering cross-site auto-play media, comprising:

a response parser executed on a data processing system having one or more processors and memory, configured to;

receive a request for media content at a first domain embedded in a content slot from a second domain, the request including a predefined identifier indicating that the client device is configured to restrict cross-domain redirection and a host header, the host header of the request having an address to a media content element to render in the content slot, and

determine, responsive to identification of the first domain as different from the second domain and to identification of the predefined identifier indicating that the client device is configured to restrict cross-domain redirection, that the request comprises a content type header having a first predetermined value; and
