System and method for serving online synchronized content from a sandbox domain via a temporary address

A system comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
• receiving, at a first domain via a first uniform resource locator (URL) directed to the first domain, a first request from a user to access a content item stored in the system;
• generating a second URL directed to a second domain and associating the second URL with the content item;
• receiving a second request to access the content item via the first URL combined with a predefined query parameter;
• redirecting the second request to the second URL;
• and
• serving the content item from the second domain in response to the second request.

A non-transitory computer-readable storage device storing instructions which, when executed by a processor, cause the processor to perform operations comprising:

• receiving, at a first domain via a first link directed to the first domain, a first request associated with a content item stored in an online content management system;
• in response to the first request, generating a second link directed to a second domain and associating the second link with the content item;
• receiving, at the second domain via the second link, a second request from a client device, the second request being associated with the content item;
• when it is determined that the second link is being accessed for a first time since the second link was generated:
• generating a session identifier for the second link;
• issuing the session identifier to the client device;
• and
• serving the content item from the second domain to the client device in response to the second request;
• and
• when it is determined that the second link is not being accessed for the first time since the second link was generated:
• serving the content item from the second domain to the client device in response to the second request only when the client device is in possession of the session identifier.
