Abstract

In one embodiment, a method includes accessing a profile page of a user on an online social network, accessing cached content from a syndicated feed, determining the last time the content from the syndicated 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 syndicated 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 an online social network:

receiving a request to access a web page associated with a first user of the online social network from a second user of an online social network, the online social network comprising a graph 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 a profile page of the 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, wherein the first and second users are separated by a single degree of separation in the graph structure, and wherein the second user is associated with tracking preferences;

in response to the request, accessing, at a first time, the web page associated with the first user of the online social network, the web page comprising;

a first content associated with the first user;

an identifier of a web site that is external to the online social network and an identifier of a uniform resource locator (URL) specifying a first feed for receiving updated content from the web site; and

a timer specifying a minimum lifetime for accessing cached content from the first feed;

accessing a cached content from the first feed, wherein the cached content was last updated at a second time;

determining the last time content from the first feed was updated based on the first time and the second time;

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

else, accessing the first feed for the web site, wherein the first feed comprises updated content from the web site, and updating the web page associated with the first user to include the updated content; and

sending a notification to the second user that the web page associated with the first has updated content if the updated content is a type of content that substantially matches the tracking preferences.

2. The method of claim 1, wherein the web page further comprises a timer specifying a maximum lifetime for accessing cached content from the first feed, the method further comprising, if the last time the content from the first feed was updated was after the maximum lifetime, then accessing the first feed for the web site and updating the web page associated with the first user to include the updated content.

3. The method of claim 1, further comprising:

accessing the tracking preferences of the second user, wherein;

the tracking preferences identify the first user, one or more types of activity related to content the second user want to track, and a URL specifying a second feed for notifying the second user when content is updated;

determining whether the web page associated with the first user comprises updated content;

if the web page associated with the first user 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 sending a notification to the second user that the web page associated with the first user has updated content, wherein the notification is sent to the second user by the second feed.

4. The method of claim 3, wherein the notification comprises an activatable link to the web page of the first user.

5. The method of claim 3, further comprising displaying the first content and the updated content to the second user.

6. The method of claim 3, wherein one of the types of activity related to content the second user wants to track is activity related to photographs.

7. The method of claim 3 wherein one of the types of activity related to content the second user wants to track is activity related to videos.

8. The method of claim 3, wherein one of the types of activity related to content the second user wants to track is activity related to blogs or blog posts.

9. The method of claim 3, wherein one of the types of activity related to content the second user wants to track is activity related to profile information.

10. The method of claim 3,

wherein the online social network comprises a graph 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 a profile page of the 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;

and

wherein one of the types of activity related to content the second user wants to track is activity related to information regarding connections between the nodes in the graph structure.

11. The method of claim 1, wherein the web page associated with the first user is a profile page of the first user on the online social network.

12. The method of claim 1, wherein the cached content or updated content is a photograph and the web site is a photo sharing web site.

13. The method of claim 1, wherein the cached content or updated content is a video and the web site is a video sharing web site.

14. The method of claim 1, wherein the cached content or updated content is a blog or blog post and the web site is a blogging web site.

15. The method of claim 1, further comprising a notification to the second user one or more second users of the online social network that the web page associated with the first user has updated content.

16. The method of claim 1, wherein the first feed is a RSS feed.

17. The method of claim 15, wherein the notification is sent to the second user transmitted to by a second feed for notifying the second user when content is updated.

18. 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 web page associated with a first user of the online social network from a second user of an online social network, the online social network comprising a graph 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 a profile page of the 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, wherein the first and second users are separated by a single degree of separation in the graph structured, and wherein the second user is associated with tracking preferences;

in response to the request, access, at a first time, the web page associated with the first user of the online social network, the web page comprising;

a first content associated with the first user;

an identifier of a web site that is external to the online social network and an identifier of a uniform resource locator (URL) specifying a first feed for receiving updated content from the web site; and

a timer specifying a minimum lifetime for accessing cached content from feed;

access a cached content from the first feed, wherein the cached content was last updated at a second time;

determine the last time content from the first feed was updated based on the first time and the second time;

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

else, access the first feed for the web site, wherein the first feed comprises updated content from the web site, and updating the web page associated with the first user to include the updated content; and
