Abstract

Methods and apparatus are provided for providing customized domain messages. A customized message for one of a plurality of domains is received at one of a plurality of servers of a content delivery network. A request is received from a user device for content for the one of the plurality of domains at the one of the plurality of servers. The customized message is provided by the one of the plurality of servers to the user device in response to the request when the one of the plurality of domains is unavailable.

Claims

1. A method comprising the steps of:

receiving a customized message for one of a plurality of domains at one of a plurality of servers of a content delivery network;

receiving a request from a user device for content for the one of the plurality of domains at the one of the plurality of servers; and

providing, via the one of the plurality of servers, the customized message to the user device in response to the request when the one of the plurality of domains is unavailable.

2. The method of claim 1, wherein the customized message comprises an error message for the one of the plurality of domains for display when the content for the one of the plurality of domains is unavailable.

3. The method of claim 1, further comprising the steps of:

providing an inquiry to a database service via the one of the plurality of servers in response to the request;

receiving a notification from the database service at the one of the plurality of servers when the content for the one of the plurality of domains is unavailable, wherein the customized message is provided by the one of the plurality of servers to the user device after the notification is received.

4. The method of claim 3, wherein the database service includes an application server, and the step of receiving the notification comprises the step of:

receiving the notification from the database service at the one of the plurality of servers when the application server is unavailable.

5. The method of claim 4, wherein:

the database service comprises a multi-tenant on-demand database service; and

the one of the plurality of domains corresponds to a tenant of the multi-tenant on-demand database service.

6. The method of claim 1, further comprising the steps of:

receiving a second customized message for a second one of the plurality of domains at the one of the plurality of servers;

receiving a second request from the user device for second content for the second one of the plurality of domains at the one of the plurality of servers; and

providing, via the one of the plurality of servers, the second customized message to the user device in response to the second request when the second content for the second one of the plurality of domains is unavailable.

7. The method of claim 6, further comprising the steps of:

storing the customized message on the one of the plurality of servers; and

storing the second customized message on the one of the plurality of servers.

8. A method executable by an application server, the method comprising the steps of:

receiving, at the application server, a customized message for a particular domain, wherein the customized message comprises formatted information for display on a browser application; and

providing, from the application server, the customized message to a content delivery network for storage on a plurality of content delivery network servers for delivery in response to requests received at one of the plurality of content delivery network servers from the browser application when a user of the browser application seeks to access the particular domain and the particular domain is unavailable.

9. The method of claim 8, wherein the particular domain corresponds to a tenant of a multi-tenant on-demand database service.

10. The method of claim 8, wherein the customized message comprises an error message for the particular domain for display when content for the particular domain is unavailable.

11. The method of claim 8, further comprising the steps of:

receiving, at the application server, a second customized message for a second particular domain, the second particular domain being different from the particular domain, and the second customized message being different from the customized message; and

providing, from the application server, the second customized message to the content delivery network for storage on the plurality of content delivery network servers for delivery in response to requests received from the browser application when the user seeks to access the second particular domain.

12. The method of claim 8, further comprising the steps of:

receiving a request for content for the particular domain from one of the plurality of content delivery network servers; and

providing, via the application server, the content for the particular domain to the one of the plurality of content delivery network servers in response to the request when the content for the particular domain is available.

13. The method of claim 12, further comprising the step of:

providing, via an alternate cache server, a notification to the one of the plurality of content delivery network servers, to thereby instruct the content delivery network to provide the customized message, in response to the request when the content for the particular domain is unavailable.

14. The method of claim 13, further comprising the step of:

determining, via the monitoring server, whether the application server is available, wherein the monitoring server provides the notification to the one of the plurality of content delivery network servers when the application server is unavailable.

15. A content delivery network comprising:

a plurality of servers, each of the plurality of servers configured to;

receive a customized message for one of a plurality of domains;

receive a request from a user device for content for the one of the plurality of domains; and

provide the customized message to the user device in response to the request when the one of the plurality of domains is unavailable; and

a memory coupled to the plurality of servers and configured to store the customized message.

16. The content delivery network of claim 15, wherein the customized message comprises an error message for the one of the plurality of domains for display when the content for the one of the plurality of domains is unavailable.

17. The content delivery network of claim 15, wherein the one of the plurality of servers is further configured to:

provide an inquiry to a database service via the one of the plurality of servers in response to the request;

receive a notification from the database service at the one of the plurality of servers when the content for the one of the plurality of domains is unavailable; and

provide the customized message to the user device after the notification is received, provided that the one of the plurality of domains is unavailable.

18. The content delivery network of claim 17, wherein:

the database service includes an application server; and

the one of the plurality of servers is further configured to receive the notification from the database service when the application server is unavailable.

19. The content delivery network of claim 18, wherein:

the database service comprises a multi-tenant on-demand database service; and

the one of the plurality of domains corresponds to a tenant of the multi-tenant on-demand database service.

20. The content delivery network of claim 15, wherein the one of the plurality of servers is further configured to:

receive a second customized message for a second one of the plurality of domains at the one of the plurality of servers;

receive a second request from the user device for second content for the second one of the plurality of domains at the one of the plurality of servers; and

provide the second customized message to the user device in response to the second request when the second content for the second one of the plurality of domains is unavailable.
