A method and an apparatus that configure a sandbox document for secure presentation of a block of data stored in the sandbox document in response to an editing request from a client are described. A presentable content corresponding to a document may be sent to the client for editing. The document and the sandbox document may be separately addressable by separate paths of separate domains. The editing request may include the block of data to update the presentable content of the document. The updated presentable content may include a hyperlink to the sandbox document. The edited document and the sandbox document may allow secure presentation of the block of data within the updated presentable content of the edited document without a need to filter the block of data.
