1. A machine-readable non-transitory storage medium having instructions therein, which when executed by a machine, causes the machine to perform a method, the method comprising: in response to receiving a first request associated with a document, updating the document in a first domain, the updated document associated with a mechanism for secure activation of active content referred to by a hyperlink; storing the active content in a second domain without filtering the active content; in response to receiving a subsequent request from a client to retrieve the updated document in the first domain, generating, at a device, a one time token uniquely for the subsequent request, the one time token to authorize an access to the active content of the second domain via a hyperlink having the one time token; sending the updated document modified with the hyperlink having the one time token to the client, the active content accessible via the hyperlink having the one time token when the client presents the updated document; in response to receiving a second request addressing the active content of the second domain, extracting a token from the second request, the token dynamically generated for a request to retrieve the updated document in the first domain; verifying, at the device, whether the second request is valid using the token extracted from the second request, the second request being valid when the token matches the one time token; and sending the active content for the second request if validity of the second request is verified based on the token to allow the secure activation of the active content in the updated document.
