Abstract

A computer implemented method includes receiving an object scheduled for automatic deletion after a specified viewing period, a specified number of views or a specified period of time. Object push criteria are evaluated. The object is pushed to an edge server cache in response to evaluating. The object is served in response to a request for the object.

Claims

1. A computer implemented method, comprising:

receiving an object scheduled for automatic deletion after a specified viewing period, a specified number of views or a specified period of time;

evaluating object push criteria;

pushing the object to an edge server cache in response to evaluating;

serving the object in response to a request for the object; and

deleting every instance of the object, wherein deleting comprises;

deleting every instance of the object except one instance,

serving the one instance, and

deleting the one instance.

2. The computer implemented method of claim 1 wherein the object is a message.

3. The computer implemented method of claim 1 wherein the object is a message with an accompanying picture.

4. The computer implemented method of claim 1 wherein the object is a message with an accompanying video.

5. The computer implemented method of claim 1 wherein the object push criteria includes content delivery network traffic patterns.

6. The computer implemented method of claim 1 wherein the object push criteria includes historical use patterns of a user.

7. The computer implemented method of claim 1 wherein the object push criteria includes a social graph associated with a user.

8. The computer implemented method of claim 1 wherein the object push criteria includes geolocation information.

9. The computer implemented method of claim 1 further comprising ascribing a cache management rank to the object.

10. The computer implemented method of claim 1 wherein deleting is performed after serving the ephemeral object.

11. The computer implemented method of claim 1 further comprising checking for an object deletion problem.

12. The computer implemented method of claim 11 further comprising disabling an edge server in response to an object deletion problem.
