Delivering, such as in response to request from a browser, the content resource with the modified embedded resource.

Abstract: A computer-implemented method in a content delivery network (CDN), wherein the CDN delivers content on behalf of at least one content provider. The method includes: a first server: receiving a request from a client for particular content; determining at least one delivery server in the CDN; migrating the request to the at least one delivery server; and then providing the least one delivery server with first network traffic from the client. Then a second server, distinct from the first server, determines information about the least one delivery server; and then, based on the determining, provides the least one delivery server with second network traffic from the client.

Abstract: A server in a content delivery (CD) network that distributes content on behalf of one or more subscribers. Responsive to a request from a client for a particular resource, if the particular resource is already in a cache on the server, serving the particular to the client from the cache; otherwise if the particular resource is not already cached on the server, when a count value exceeds a first threshold value, obtaining, caching, and serving the particular resource. When the count value is less than a second threshold value, obtaining and serving the particular resource. When the count value is: (i) not less than the second threshold value, and (ii) not greater than the first threshold value, then obtaining the particular resource and selectively caching the particular resource; and serving the particular resource to the client.

The selected server determines whether it is responsible for the request and may hand it off to another cluster member.

Abstract: A computer-implemented method on a device in a content delivery (CD) network. The device has hardware including storage with at least one first class of storage and at least one second class of storage, the first class of storage being faster than the second class of storage.

The method includes obtaining log event data from at least one component or service on the device that is to be delivered to a component or service on a distinct device. Each log event data item has a priority. If a connection to an external location is lost, at least some of the log event data items are selectively stored in the storage, wherein the storing is based on priority of the log event data items. Otherwise, if the connection is not lost, at least some of the log event data items are sent to the at least one external location.
