Abstract

In one embodiment, a method includes accessing a profile page of a user on an online social network, accessing cached content from a feed, determining the last time the content from the feed was updated, and if the last time the content was update was before a particular time, then updated the profile page of the user to include the cached content, else, accessing the feed and updating the profile page of the user to include updated content.

Claims

1. A method comprising, by one or more computer systems of a social networking system:

receiving a request to access a first page from a first user of the online social network, the first user being associated with tracking preferences identifying one or more types of activity related to one or more types of content that the first user would like to track on feeds that are external to the online social network;

in response to the request, accessing, at a first time, one or more feeds associated with one or more second users of the online social network, each feed being external to the online social network and comprising content associated with the respective second user, and each second user being connected to the first user within the online social network;

determining, for each external feed, whether an external content source associated with the external feed comprises updated content, wherein the updated content is a type of content that substantially matches the tracking preferences of the first user;

for each external feed associated with an external content source having updated content, updating the first page to include updated content from the external feed if the last time content from the external feed was updated was after a minimum lifetime for accessing cached content from the external feed, wherein the cached content was received from the external feed at an elapsed time that is more than the minimum lifetime; and

sending the first page with the updated content to the client system of the first user for display.

2. The method of claim 1, wherein each second user is connected to the first user within a threshold degree of separation within the online social network.

3. The method of claim 1, wherein the first page comprises one or more unique identifiers specifying the one or more external feeds.

4. The method of claim 3, wherein each unique identifier is a uniform resource locator (URL) specifying the external feed for receiving updated content from an external content source associated with the external feed.

5. The method of claim 1, wherein the first page further comprises a timer specifying the minimum lifetime for accessing cached content from the external feed.

6. The method of claim 1, further comprising receiving updated content from an external content source associated with the external feed, the external content source being external to the online social network.

7. The method of claim 1, further comprising accessing a graph data structure defining relationships between users, the graph structure comprising a plurality of nodes and information defining connections between the nodes, wherein each node corresponds to a particular user, and wherein a degree of separation between any two nodes is a minimum number of connection hops required to traverse the graph structure from one node to the other.

8. The method of claim 7, each second user being within a single degree of separation in the graph structure from the first user.

9. The method of claim 1, further comprising:

accessing a cached content from one or more of the external feeds, wherein the cached content was last updated at the second time, and wherein the last time content from the external feed was updated is determined based on the first time and the second time; and

updating the page associated with the first user to include the cached content if the last time content from the external feed was updated was before the minimum lifetime;

the last time content from the external feed was updated being less than the minimum lifetime for accessing cached content from the external feed.

10. The method of claim 9, further comprising determining the last time content from the first feed was updated based on the first time and the second time.

11. The method of claim 1, wherein the first page further comprises a timer specifying a maximum lifetime for accessing cached content from the external feed, the method further comprising, if the last time the content from the external feed was updated was after the maximum lifetime, then accessing the external feed for an external content source and updating the first page to include the updated content.

12. The method of claim 1, further comprising:

if the external content source comprises updated content, then determining whether the updated content is a type of content that substantially matches the type of activity related to content identified in the tracking preferences; and

if the tracking preferences are substantially matched, then updating the first page to include the updated content.

13. The method of claim 1, wherein one of the types of activity related to content the first user wants to track is activity related to one or more of photographs, videos, blogs or blog posts, profile information, or any combination thereof.

14. The method of claim 1, wherein the first page is a profile page of the first user on the online social network.

15. The method of claim 1, wherein the first page is a landing page of the online social network.

16. The method of claim 1, wherein one or more of the external feeds is a RSS feed.

18. The method of claim 1, wherein the first page is a web page of the online social network.

19. The method of claim 1, wherein the first page is a user interface accessed by the client system of the first user.

20. The method of claim 1, wherein the content from the external feed comprises content generated by the respective second user.

21. The method of claim 1, wherein the tracking preferences associated with the first user further identify the one or more second users whose activities the first user would like to track.

17. A system of an online social network comprising:

a memory comprising instructions executable by one or more processors; and

the one or more processors coupled to the memory and operable to execute the instructions, the one or more processors being operable when executing the instructions to;

receiving a request to access a first page from a first user of the online social network, the first user being associated with tracking preferences identifying one or more types of activity related to one or more types of content that the first user would like to track on feeds that are external to the online social network;

in response to the request, accessing, at a first time, one or more feeds associated with one or more second users of the online social network, each feed being external to the online social network and comprising content associated with the respective second user, and each second user being connected to the first user within the online social network;

determining, for each external feed, whether an external content source associated with the external feed comprises updated content wherein the updated content is a type of content that substantially matches the tracking preferences of the first user;

for each external feed associated with an external content source having updated content, updating the first page to include updated content from the external feed if;

the last time content from the external feed was updated was after a minimum lifetime for accessing cached content from the external feed, wherein the cached content was received from the external feed at an elapsed time that is more than the minimum lifetime; and

sending the first page with the updated content to the client system of the first user for display.
