Abstract

A content management system implementing methodologies providing retroactive shared content item links is disclosed. The content management system and methodologies allow a team administrator of a team to configure a team-wide shared link policy that determines whether non-team members can access content items associated with team accounts using shared links generated for the content items by team members. The team shared link policy has two settings. In a first setting, the content management system allows non-team members to use shared links generated by team members to access content items associated with team accounts. In a second setting, the content management system blocks access to the content items by non-team members. Shared links are retroactive in the sense they do not need to be regenerated after the team shared link policy has been changed from the second setting back to the first setting.

First claim

The invention claimed is:

1. A method performed by one or more processors of a content management system, the method comprising:
generating a unique link for a content item;
at a first time, receiving, via at least one of the one or more processors, from a first client device of a first user of the content management system, a first request to access the content item using the unique link;
in response to receiving the first request to access the content item:
determining, via at least one of the one or more processors, a team, comprising one or more members, that is associated with the content item;
wherein the first user is not a member of the team;
determining, via at least one of the one or more processors, that a current setting of a team shared link policy of the team is a first setting of at least two different setting options for the team shared link policy;
in response to determining that the current setting of the team shared link policy is the first setting, returning, via at least one of the one or more processors, a response to the first client device of the first user that indicates that the first user is not permitted to access the content item;

at a second time, receiving, via at least one of the one or more processors, from a second client device of a second user of the content management system, a second request to access the content item using the unique link;
in response to receiving the second request to access the content item:
determining, via at least one of the one or more processors, the team, comprising the one or more members, that is associated with the content item;
wherein the second user is not a member of the team;
determining, via at least one of the one or more processors, that the current setting of the team shared link policy of the team is a second setting of the at least two different setting options for the team shared link policy;
in response to determining that the current setting of the team shared link policy is the second setting, returning, via at least one of the one or more processors, a response to the second client device of the second user that comprises at least a portion of the content item.

2. The method of claim 1 , further comprising, prior to receiving the first request and the second request:
receiving, at the content management system, a request by a member of the team to generate the unique link.

3. The method of claim 1 , further comprising, prior to receiving the first request and the second request, storing the unique link in an association with an identifier of the content item.

4. The method of claim 1 , further comprising, prior to receiving the first request and the second request, the content management system not sending the unique link to the first user or the second user.

5. The method of claim 1 , wherein the first user or the second user is an anonymous user that does not have a user account with the content management system.

6. The method of claim 1 , further comprising returning, via at least one of the one or more processors, the response to the second client device of the second user that comprises at least the portion of the content item only after determining that no other access controls prohibit the second user from accessing the content item.

7. The method of claim 1 ,
wherein the second time is later than the first time.

8. A content management system comprising:
one or more processors;
one or more computer-readable media storing one or more computer programs for execution by the one or more processors, the one or more computer programs comprising instructions for:
generating a unique link for a content item;
at a first time, receiving, via at least one of the one or more processors, from a first client device of a first user of the content management system, a first request to access the content item using the unique link;
in response to receiving the first request to access the content item:
determining, via at least one of the one or more processors, a team, comprising one or more members, that is associated with the content item;
wherein the first user is not a member of the team;
determining, via at least one of the one or more processors, that a current setting of a team shared link policy of the team is a first setting of at least two different setting options for the team shared link policy;
in response to determining that the current setting of the team shared link policy is the first setting, returning, via at least one of the one or more processors, a response to the first client device of the first user that indicates that the first user is not permitted to access the content item;

at a second time, receiving, via at least one of the one or more processors, from a second client device of a second user of the content management system, a second request to access the content item using the unique link;
in response to receiving the second request to access the content item:
determining, via at least one of the one or more processors, the team, comprising the one or more members, that is associated with the content item;
wherein the second user is not a member of the team;
determining, via at least one of the one or more processors, that the current setting of the team shared link policy of the team is a second setting of the at least two different setting options for the team shared link policy;
in response to determining that the current setting of the team shared link policy is the second setting, returning, via at least one of the one or more processors, a response to the second client device of the second user that comprises at least a portion of the content item.

9. The content management system of claim 8 , wherein the one or more computer programs further comprise instructions for:
prior to receiving the first request and the second request:
receiving, at the content management system, a request by a member of the team to generate the unique link.

10. The content management system of claim 8 , wherein the one or more computer programs further comprise instructions for:
prior to receiving the first request and the second request, storing the unique link in an association with an identifier of the content item.

11. The content management system of claim 8 , wherein the one or more computer programs further comprise instructions for:
prior to receiving the first request and the second request, the content management system not sending the unique link to the first user or the second user.

12. The content management system of claim 8 , wherein the first user or the second user is an anonymous user that does not have a user account with the content management system.

13. The content management system of claim 8 , wherein the one or more computer programs further comprise instructions for:
returning the response to the second client device of the second user that comprises at least the portion of the content item only after determining that no other access controls prohibit the second user from accessing the content item.

14. The content management system of claim 8 ,
wherein the second time is later than the first time.

15. One or more non-transitory computer-readable media storing one or more computer programs for execution by one or more processors of a content management system, the one or more computer programs comprising instructions for:
generating a unique link for a content item;
at a first time, receiving, via at least one of the one or more processors, from a first client device of a first user of the content management system, a first request to access the co
